mac classic lcd screen free sample
There are only 4 screws on the back of the Classic II that hold the case together. Two on the bottom near the ports, and two on the top near the built in handle. Removal of the two near the handle require a longer tool to reach in the deep sockets. Once the screws are removed, it was a little difficult prying the front panel from the rear. I am not sure if it is designed that way or if it was the age of the plastic. Essentially the internals are mounted on a frame and screwed to the front panel, so the back is just a cover.
I searched around and found others who have done a similar mod. There are really no high definition panels out there in this small of a size. I suppose an iPad mini with retina display at 7.9 inches would be high resolution, but good luck finding a driver for it. The best I could find was 8.0 inches at 1024x768. There are plenty of 800x600, but I wanted the best I could find. I could not find anything between 8 and 9, as 8.7 would have been optimal. The 1994 Color Classic had a 10" CRT with 512x384 resolution. The Classic II had 9" monochrome CRT 512x342. My mod has a smaller screen and 4x the pixels.
The screen I chose was off eBay, a kit with LVDS driver board. When I received it, initially it worked great, then it fizzled out. I think it was a bad driver board, so I ordered a separate replacement, and it failed to work as well. I then thought it was possibly the screen so I ordered a 2nd screen. The 2nd one was dim, so I ordered a 3rd screen. Still dim, so ordered a 3rd board, different design. Screen one was confirmed dead, screen 2 and 3 worked fine with board 3. Lots of waste on this project, SMH.
The driver board supports multiple inputs (VGA, HDMI, composite 1 and 2). There are on screen controls to adjust the typical LCD monitor and the original controller came with an IR remote as well as a control panel. The 3rd driver board did not have the IR sensor mounted, so I stole it from the first fried controller. Since the original Classic II had tube monitor adjustments hidden on the rear behind a detachable panel, I thought that was the ideal place to put this screen control panel as well. I had to design and 3D print an interface panel, and figure out how to mount it, and then cut out a hole for it in the back case. I could not see the button icons when printed in black, so I printed them in white for the contrast. The internal VGA out from the GT730 drives the LCD VGA input. The HDMI input is directed to the rear panel so this Classic II can be used as an external monitor (just a pure goofy effect). The HDMI from the GT730 goes to the rear panel so you can drive an external monitor with this Hackintosh (think HTPC in the living room, or large desktop monitor).
My first premise: Conservate all components of the Mac Classic, don´t break anything, or alterate something that has no reverse gear. I have saved all original components, and lets go to start with it. Who knows, maybe 10 years from now I get to mount the Vintage Macintosh again.
When the Macintosh arrived, I see that the color is very... yellow... . Yes, its a machine with more than 30 years old, and formerly the cases of these Computer are make with a bromine compound, to act as a fire retardant...curious, but with years, its provocate this color on these components (Computer, keyboard, mouse, etc... ). I searched on the WEB, and find a method that call RETROBRIGHT, there are a lot of technies to apply them (you can find it in google too), but I applied the one that i Read the mosts positive comments, and the less complicated method for me.
My Proccess: 3 days of apply the product and 8 hours per day in the Sun (the was no bright sun, they were somewhat cloudy days). Some days, I wrapped the Macinstosh with transparent paper, but my recommendation is no use this paper, because this make me some stain on the plastic. And for that, I applied some days more the proccess, so that they would disappear as much as possible. With these word, I wanted to tell you that this proccess exists, and I obtained a very good results, but not a perfect result. Constantly monitor the proccess result, dont leave the product in the sun, and return when the 8 hours pass.
Later, i washed very well the Macinstosh, with a non-abrasive sponge, and a neutral soap. Dry very well with a soft cloth, and the next day, when its dry completely, I applied a special lacquer (as a UV protector, to delay the reapperance of the yellowish color... yes, that color will return after a time, hopefully many years). Here the lacquer I use (glossy finish).
My Model is Apple Design Keyboard and Mouse. They have some Yellow color like Macintosh, but with some retrobright session (more easily process than other), them looks perfectly. I clean all the internal pieces, dismount everything, and clean with Isopropyl alcohol. Here you are a photo of them (you can see the difference between the photos of the first post):
First, I tried to put one more modern Keyboard, but the connector of this machine is ADB (Apple Device Bus), and i thought that its a PS2 connector... bad luck. For a looking on Google, I found some cable, but so expensive, and finally, I learned that ADB is the identical that a S-VIDEO connector. And you can find a lot of cheap offers of S-VIDEO connectors, I bought one and mounted (sold require). For this model of keyboard, the wire is directly connect to his motherboard, other model have an individual wire... .
I think that it was a correct decisión, because I wanted use it for Music, Games (I am not a full gamer), Video, and something else... . And because the Macinstosh Classic is an original machine, I wanted use the original component for Raspberry (I bought too some fun details, that I mush show you later
First: When I bought the Macintosh, I believed that screen is broken. Consequently, I want to take advantage of the CRT Crystal, for make my own new Screen (insert a LCD, maybe 7-8 inch into de CRT Crystal). I saw some videos for people that cut the original CRT Crystalwith a Dremel (with a diamond edge), and I thought that it maybe be a good decision. But when I managed to fix the original Macintosh, I discard this option, because as I have already told us,I want to keep the original parts instact.
Second: From discard the first option... I decided to include aLCD monitor behind the monitor case. Originally, the Macintosh Classic have a 9 inch 4:3 format Monitor (more info here, https://es.wikipedia.org/wiki/Macintosh_Classic), but when I use it, I saw that the monitor have a black overscan. The people that make a similar project, includes a LCD for 8 inch (most popular in store), but I want to aproach the maximun of the hole for the monitor. I discart the option for a LCD with too much overscan).
Third (and finally): I want a really good Screen, because honestly, it will be the most eye-catching for the project. After some WEB analizyng, I decided to buy this option: https://shop.pimoroni.com/products/hdmi ... t-1024x768, a 10 INCH SCREEN 4:3 FOMAT for PIMORONI. I thought too for the Screen LCD for IPAD, but it was to much expensive, and I read that have some dificults to configure and install.
- The screen (with his frame) is bigger than the hole for the monitor. But I think and search a lot for make a solution. You can config the Overscan for your PI, to displace the screen image. I will explain this step in the furure.
- The Hole is curve: The original Macintosh have a CRT curve monitor, and the LCD is flat, I want to resolve this for make a beatifull finish. Some people put the monitor behind, and ignore de the curve (badly finish for me), but I found a person that make a 3D frame for this project, to hide this curve between the LCD and the Case. Here I bring yoy the URL for this: https://www.thingiverse.com/thing:3551263 (I printed it with a good quality material). I reuse the original up screw for the Macintosh, to hold the screen well. Here the detail of the finish:
- Protection the LCD Panel: I bought a transparent acrylic panel (1mm thickness), and with that, make the LCD protection, and a structure to put the mainboard for the screen (some similar like a view for the PICADE projoect, that mount this screen). In summary and iin order: Front Case, 3DBezel, Acrylic, Screen, Acryclic. Here the structure with acrylic panel:
Finally, the results for me is very very good. But I"m still giving it a spin, for aproach all the hole size (now I have a besel of 2-3 mm that not have image). To do this, I want to rotate the Screen image, because the original orientation of the screen, dificult me the project. Even so, i like so much. The detail for the actual overscan (that i want to fix later):
I said every times, that I want to conservate the original structure for the Macintosh, and for that, I thought to make a steal real panel, similar of the original motherboard of the Macintosh. WIth this, I can use the can use the same mechanism to anchor the steal rear panel. 1mm thickness steal panelspecifically. Hera some photos:
I want to put the power on/off button outsite de case of the Macinstosh. First I thought to use the left side button for the Macintosh, to push the Pi button power, but its very delicate, and discarded this option.
Then, the longitude for the original button power cable for the PI was so short, and its dificult to distribute the PI inside the Macintosh. I tried to use and extension cable(Male USB-C - Female USB-C) for make a solution for it, but these option lose some power for the PI, and the system became unstable.
When I connect the PI to the Screen, and all the other connect for all connector, I saw that the PI Screen start to blink, I analize the power of the PI, and read that all USB connector can give a power of 1200 mA (total). And that is insuficient for all my connected device:
The solution, I use a whole for the rear panel to put and extra USB (Female), who are connect directly to the power of the Screen (with an mobile power adapter). Then I have the enought energy for all the connector.
Distribution (Left to Right on the image): Power On/Off Button - USB 2.0 for Screen Power - Pi Power Connector - HDMI Second Screen Connector - One free hole - ADB Connector - Jack Audio Connector.
Bonus: I put an USB 3.0 Connector on the front of the Macintosh, in the hold of the Disket. The truth is that it is very concealed, and it is very useful.
Its the moment to tell us how I connect a vintage Macintosh Keyboard&Mouse, to a moder PC, Raspberry or similar. First, I thougth to buy a new keyboard for this project, but when I searches about similar project, I read something about some people that came to live his old Mac Keyboards. There is an ADB-USB Adapter that can help you to do it. I found various alternative on google, but for me its important 2 things:
I have never worked with Raspberry PI until this project. So, I read a lot about which OS to install. In this proccess, I found a posibility to install a OS, that emulated the appearance of MacOS... a Macintosh Classic from 30 years ago, with an actuallyOS...this sound good.
I decided to install Twistter OS, this is a very good OS for Raspberry (only for PI 4), that you can emulated the OS for Macos, Linux, or Windows... . Here you can download it, and read more about (https://twisteros.com/). The WEB have a DISCORD support too, that work very good (I solve some problems with it).
Here you can see the MacOS Desktop config, with the Apple Toolbar and Icon, it looks great. Switch Desktop theme is very simple, you only will to select the one you want, and Twister confir all for you (in next reboot).
You know that I put a big Screen on my Macintosh Classic (10 inch), and I make a solution for center the image, this function calls overscan on PI World.
2. Config your overscan parameter: You can edit the file /boot/config.conf (pi is my user, you must replace it in the url). Here is mine configuration, but remember that I put my Screen reverse (phisicaly):
I also configure a new personalize Splash Image for the boot sequence os the PI, something like new and old Macintosh computer, with the two logos, that I make with Procreate (Ipad Pro). If you see with detail, you can see some Easter Egg for Raspberry PI too
We know the classic Mac fans in the audience won’t be happy about this one, but the final results are simply too clean to ignore. With a laser-cut adapter and a little custom wiring, [Travis DeRose] has come up with a repeatable way to modernize a Compact Macintosh (Plus, SE, etc) by swapping out all of its internals for an iPad mini.
He goes over the whole process in the video after the break, while being kind enough to spare our sensitive eyes from having to see the Mac’s enclosure stripped of its original electronics. We’ll just pretend hope that the computer was so damaged that repair simply wasn’t an option.
Those with some first hand iPad experience might be wondering how you wake the tablet up once the Mac is all buttoned back up. That’s an excellent question, and one that [Travis] wrestled with for awhile. In the end he came up with a very clever solution: he cuts into a charging cable and splices in a normally-closed momentary push button. Pushing the button essentially “unplugs” the iPad for a second, which just so happens to wake it up. It’s an elegant solution that keeps you from having to make any modifications to that expensive piece of Apple hardware.
This is the experience a computer user would have had every time she booted up her Macintosh SE, a popular all-in-one computer sold by Apple from 1987 to 1990. By today’s standards the machine is a dinosaur. It boasts a nine-inch black-and-white display. Mine came with a hard disk that offers 20 megabytes of storage, but some lacked even that luxury. And the computer still would have cost a fortune: The version I have retailed for $3,900, or about $8,400 in 2019 dollars.
That’s a lot of money. It’s one of the reasons why computers weren’t as universal three decades ago as they are today, especially at home. In 1984, when the Macintosh first appeared, about 8 percent of U.S. homes had a computer; five years later, when the computer I’m writing on was sold, that figure had risen to a whopping 15 percent.
That made for a totally different relationship to the machine than we have today. Nobody used one every hour—many people wouldn’t boot them up for days at a time if the need didn’t arise. They were modest in power and application, clunking and grinding their way through family-budget spreadsheets, school papers, and games.
The original Macintosh was an adorable dwarf of a computer. About the size of a full-grown pug, its small footprint, built-in handle, and light weight made it easy to transport and stow. Perched on a single, wide paw, the machine looks perky and attentive, as if it’s there to serve you, rather than you it.
The whirring drone wasn’t an original feature. Steve Jobs insisted on shipping the Macintosh without a cooling fan, to make it run quietly, but by the time this model appeared he had been pushed out of the company, largely on account of how he’d run the Macintosh division. The introduction of Macintosh hard disks in 1985 had ended the machine’s silent service anyway; the SE got one inside the machine, and its smooth bezel was replaced by a more aggressive, vented one: a kind of goblin version of the endearing original.
My affection persists, though. I feel comfortable addressing this little machine. Now that laptops are ubiquitous, working on a computer at a desk is an ergonomic misery. At coffee shops and co-working spaces, people hunch over them, staring down toward screens perched at table level. Laptops are even common in offices now, because their portability allows workers to take the job into the field with them—or more likely, to bring it home. Older desktop machines sat monitors higher up, either atop the machine itself, as the Apple II did, or in an all-in-one design, like my Mac SE. The result has me looking directly at the screen, no hunching required.
Then there’s the simplicity. Everyone knows that the great triumph of the Macintosh was its ease of use. Unlike DOS or Unix workstations, and even unlike Apple’s earlier computers, the Mac’s graphical user interface freed consumer computing from esoteric commands. The design was never intuitive, to use a term often applied to it: The metaphor of folders, files, and a desktop, operated via overlapping windows, still required considerable new knowledge, even if that knowledge could be learned quickly. But it wasn’t user-friendliness alone that made computers of this era great—it was simplicity. Mousing, dragging, and menuing does make the machine easier to learn how to use than punching in commands by keystroke. But after that, the plainness of its operation is more important. A 1980s Mac offers only a handful of useful features. (Once Windows 3.0 arrived on the scene, in 1990, that truth applied to a PC as much as a Macintosh.)
On my modern MacBook Pro, a million things are happening at once. Mail retrieves email, sounding regular dings as it arrives. Dispatches fire off, too, in Messages, in Skype, in Slack. Attention-seeking ads flash in the background of web pages, while nagging reminders of Microsoft Office updates bounce in the dock. News notifications spurt out from the screen’s edge, along with every other manner of notices about what’s happening on and off the machine. Computing is a Times Square of urge and stimulus.
By contrast, the Macintosh SE just can’t do much. It boots to a simple file manager, where I face but a few windows and menu options. I can manage files, configure the interface, or run programs. It feels quiet here, despite the whirring noise. At least it’s literal noise, in the ears, instead of the ethereal kind that bombards my faculties on the MacBook Pro.
There aren’t many programs worth running on this old machine, anyway. I installed Pyro, a popular screen saver of the era, and Klondike solitaire, as if I couldn’t distract myself with my iPhone instead. Even within the programs that made people spend money on computers, simplicity reigns. I’m writing in Microsoft Word 4.0, which was released for this platform in 1990. More sophisticated than MacWrite, Apple’s word processor, the program is still extremely basic—the only reason I chose Word was so I could open the file on my modern Mac to edit and file it.
There’s not much to report; it’s a word processor. A window displays the text I am typing, whose fonts and paragraphs I can style in a manner that was still novel in the 1980s. Footnotes, tables, and graphics are possible, but all I really need to do is produce words in order, a cruel reality that has plagued writers for millennia. Any program of this era would have afforded me the important changes computers added: moving an insertion point with the mouse, and seeing the text on-screen in a manner reasonably commensurate with how it would appear in print or online.
In fact, the only feature that’s missing, from a contemporary writer’s perspective, is the capacity to add hyperlinks. That idea had been around for a couple of decades by the time the Macintosh SE came out, but Tim Berners-Lee wouldn’t develop the first web browser until 1989, a year after this computer was manufactured and a year before this copy of Word was released. Of course, it doesn’t matter much, since I can’t go online with this machine (at least, not without adding a modem, and software that wouldn’t become available for another half decade or so).
The many writing tools that today promise to encourage focus and attention are just racing to catch up with a past three decades gone. Programs like WriteRoom and OmmWriter promise a spartan, distraction-free brand of productivity that was just the standard way to write on computers in 1989. Even the keyboard that came with this machine leaves out the extras: No function keys or other extras adorn its surface, which only exists for inputting text. The primitive screen also makes a difference. Today’s internet addicts sometimes set their devices to monochrome to make it less tempting to pick them up. But this Macintosh screen is already black and white, which solidifies its role as a tool for me to use rather than a sink for all my time and attention.
Even the tiny, nine-inch size offers startling benefits. When I wrote about the Freewrite, a portable, hipster word processor that can save files to the cloud, I celebrated the welcome surprise of writing in the world instead of on the computer. That device is flat, with an e-ink screen. In the hands of a touch-typist, it liberates a writer from the sense of being inside the computer, fully enveloped by its overwhelming occupation of your field of vision, and thereby of your attention and ideas. It combats a neglected terror, where what is thinkable only extends as far as what the computer can present.
The all-in-one Macintosh engenders a similar experience. The screen is big enough to see clearly from a foot away, but small enough that it doesn’t overtake my vision. I can look up from it and stare around it, into the distance. Laptops, especially smaller ones, afford something similar, but they also contain the effort of all labors and pleasures; there’s no need, nor desire, ever to look up from one. The Macintosh is portable, handle and all, because it likely would have been put away when its owner wasn’t working on it.
Then, small screens were the norm, first in dedicated word processors, and then in desktop computer monitors, too. The Mac SE’s tiny screen wouldn’t have seemed so tiny back then; even the largest ones were only a few inches bigger. Well into the 1990s, a 17-inch computer monitor would have been heavy and costly, a luxury relegated almost exclusively to professionals.
Even televisions were smaller in this era. A 13-inch TV wouldn’t have been uncommon, and a standard set measured about 25 inches. That made both the television and the computer less prominent in, but more fused with, the home (or work) environment—and, counterintuitively, it did so by receding more into the background. It’s easy to forget a machine’s context of use so long after its equipment has vanished. That history cannot be re-created in software emulation alone. Even when computers became everyday fixtures, they did so away from ordinary life: on out-of-the-way credenzas behind workplace desks or in the covert shadow of basement offices. One would have to go to it, rather than carrying it everywhere. The device was often shared, especially in the home, making it an accessory to life, rather than life itself. It’s hard not to long for that time, given the compulsive draw of constant computing today.
Even bracketing the welcome absence of the internet, with its hurtling notices and demands, the speed of this machine’s operation changes the tenor of my work. Computers used to be slow as hell. When I first got a 386 PC in the early 1990s, I would switch it on and leave the room for a while, so it could load the BIOS, then DOS, then Windows 3.1 atop it—hard disk grinding the whole time—until finally it was ready to respond to my keystrokes and mouse clicks.
The Macintosh SE I’m writing on now boots much faster than Windows ever did, but everything here is slow too. When I open a folder, the file icons all take shape like a color squad entering formation. Loading a program like Word issues a long pause, giving me enough time to view and read the splash screen—a lost software art that provided entertainment as much as feedback. Saving a file grinds the hard disk for noticeable moments, stopping me in my tracks while the cute watch icon spins.
By comparison, today’s machines are lightning-fast. Solid-state drives make boot times and file access almost immediate. Modern multicore processors can access colossal amounts of memory, all the while wasting significant computing power through inefficiency or devoting huge amounts of machine resources to facilitate high-level software development that makes it easier to write programs. Today’s machines power through most simple tasks, such as word processing, by brute force. I don’t even notice booting my modern laptop, running a program, or saving a file anymore. Those acts have evaporated into historical memory, more and more inaccessible even to those, like me, who used the first generations of personal computers often enough to know better. Computers are faster now in every way, but the time that power has captured just gets invested in more computing time.
I glance past the small form of the Macintosh and ponder that idea while this file saves. The drone of the disk and the fan seems to lull into a resonant frequency, with the desk, the chair, and my body and brain connected to them. I wait while my document writes to disk, while Word quits, and while the Mac shuts down. It’s a strange feeling; I can’t remember the last time I shut down a computer, instead of just closing it up or letting it sleep, ready to be reanimated at the touch of a button.
The high-tech industry would characterize that act as an inconvenience, probably, imposed by the primitive technology of the past. Inevitably, in the hands of engineers and investors, the machines were bound to become faster, more powerful, more influential, more ubiquitous. And indeed they did, and now they are everywhere. My laptop is always on; my tablet is ever at the ready; my smartphone is literally in my actual hand except when I’m sleeping, if indeed I ever sleep instead of staring at it.
As I flick off the power switch on the back of the Macintosh, the whine retreats in a gentle diminuendo, until it finally gives way to silence. I have accomplished a feat that is no longer possible: My computing session has ended.
The Macintosh SE is a personal computer designed, manufactured, and sold by Apple Computer, from March 1987Macintosh Plus design and was introduced by Apple at the same time as the Macintosh II.
The SE retains the same Compact Macintosh form factor as the original Macintosh computer introduced three years earlier and uses the same design language used by the Macintosh II. An enhanced model, the SE/30, was introduced in January 1989; sales of the original SE continued. The Macintosh SE was updated in August 1989 to include a SuperDrive, with this updated version being called the "Macintosh SE FDHD" and later the "Macintosh SE SuperDrive". The Macintosh SE was replaced with the Macintosh Classic, a very similar model which retained the same central processing unit and form factor, but at a lower price point.
The Macintosh SE was introduced at the AppleWorld conference in Los Angeles on March 2, 1987. The "SE" is an initialism for "System Expansion".Macintosh Plus, were:
25 percent greater speed when accessing RAM, resulting in a lower percentage of CPU time being spent drawing the screen. In practice this results in a 10-20 percent performance improvement.
The SE and Macintosh II were the first Apple computers since the Apple I to be sold without a keyboard. Instead the customer was offered the choice of the new ADB Apple Keyboard or the Apple Extended Keyboard.
The Macintosh SE shipped with System 4.0 and Finder 5.4; this version is specific to this computer.README file included with the installation disks for the SE and II is the first place Apple ever used the term "Macintosh System Software", and after 1998 these two versions were retroactively given the name "Macintosh System Software 2.0.1".
Storage: The SE can accommodate either one or two floppy drives, or a floppy drive and a hard drive. After-market brackets were designed to allow the SE to accommodate two floppy drives as well as a hard drive, however it was not a configuration supported by Apple. In addition an external floppy disk drive may also be connected, making the SE the only Macintosh besides the Macintosh Portable which could support three floppy drives, though its increased storage, RAM capacity and optional internal hard drive rendered the external drives less of a necessity than for its predecessors. Single-floppy SE models also featured a drive-access light in the spot where the second floppy drive would be. Hard-drive equipped models came with a 20 MB SCSI hard disk.
Battery: Soldered into the logic board is a 3.6 V 1/2AA lithium battery, which must be present in order for basic settings to persist between power cycles. Macintosh SE machines which have sat for a long time have experienced battery corrosion and leakage, resulting in a damaged case and logic board.
Expansion: A Processor Direct Slot on the logic board allows for expansion cards, such as accelerators, to be installed. The SE can be upgraded to 50 MHz and more than 5 MB with the MicroMac accelerators. In the past other accelerators were also available such as the Sonnet Allegro. Since installing a card required opening the computer"s case and exposing the user to high voltages from the internal CRT, Apple recommended that only authorized Apple dealers install the cards; the case was sealed with then-uncommon Torx screws.
Upgrades: After Apple introduced the Macintosh SE/30 in January, 1989, a logic board upgrade was sold by Apple dealers for US$1,699 as a high-cost upgrade for the SE, consisting of a new SE/30 motherboard, case front and internal chassis to accommodate the upgrade components.
ROM/Easter egg: The SE ROM size increased from 64 KB in the original Mac (and 128 KB in the Mac Plus) to 256 KB, which allowed the development team to include an Easter Egg hidden in the ROMs. By jumping to address 0x41D89A (or reading from the ROM chips), it is possible to display four images of the engineering team.
Macintosh SE FDHD: Includes the new SuperDrive, a floppy disk drive that can handle 1.4 MB High Density (HD) floppy disks. FDHD is an acronym for "Floppy Disk High Density"; later some Macintosh SE FDHDs were labeled Macintosh SE SuperDrive, to conform to Apple"s marketing change with respect to their new drive. High-density floppies would become the de facto standard on both the Macintosh and PC computers from then on. An upgrade kit was sold for the original Macintosh SE which included new ROM chips and a new disk controller chip, to replace the originals.

Mac OS 8 is an operating system that was released by Apple Computer on July 26, 1997.classic Mac OS experience since the release of System 7, approximately six years before. It places a greater emphasis on color than prior versions. Released over a series of updates, Mac OS 8 represents an incremental integration of many of the technologies which had been developed from 1988 to 1996 for Apple"s overly ambitious OS named Copland. Mac OS 8 helped modernize the Mac OS while Apple developed its next-generation operating system, Mac OS X (renamed in 2012 to OS X and then in 2016 to macOS).
Mac OS 8 is one of Apple"s most commercially successful software releases, selling over 1.2 million copies in the first two weeks.pirate groups refused to traffic in the new OS, encouraging people to buy it instead.
Mac OS 8.0 introduces the most visible changes in the lineup, including the Platinum interface and a native PowerPC multithreaded Finder. Mac OS 8.1 introduces a new, more efficient file system named HFS Plus. Mac OS 8.5 is the first version of the Mac OS to require a PowerPC processor. It features PowerPC native versions of QuickDraw, AppleScript, and the Sherlock search utility. Its successor, Mac OS 9, was released on October 23, 1999.
Starting in 1988, Apple"s next-generation operating system, which it originally envisioned to be "System 8" was codenamed Copland. It was announced in March 1994 alongside the introduction of the first PowerPC Macs. Apple intended Copland as a fully modern system, including native PowerPC code, intelligent agents, a microkernel, a customizable interface named Appearance Manager, a hardware abstraction layer, and a relational database integrated into the Finder. Copland was to be followed by Gershwin, which promised memory protection spaces and full preemptive multitasking.Windows 95 to market with a development cycle of only one year.
The Copland development was hampered by many missed deadlines. The release date was first pushed back to the end of 1995, then to mid-1996, late 1996, and finally to the end of 1997. With a dedicated team of 500 software engineers and an annual budget of $250 million, Apple executives began to grow impatient with the project continually falling behind schedule. In August 1996, Apple chief technology officer Ellen Hancock froze development of CoplandNeXT and developing Rhapsody which would eventually evolve into Mac OS X in 2001 (now named macOS).
At the Worldwide Developers Conference in January 1997, Apple chief executive officer (CEO) Gil Amelio announced that, rather than release Copland as one monolithic release, Copland features would be phased into the Mac OS following a six-month release cycle. These updates began with Mac OS 7.6, released during WWDC. Mac OS 8.0, released six months later, continued to integrate Copland technologies into the Mac OS.
Released on January 19, 1998, Mac OS 8.1 was the last version of the Mac OS to run on Motorola 68000 series processors. It addressed performance and reliability improvements. It introduced a new file system named HFS+, also named Mac OS Extended, which supported large file sizes and made more efficient use of larger hard drives via using a smaller block size. To upgrade, users must reformat the hard drive, which deletes the entire contents of the drive. Some third-party utilities later appeared that preserved the user"s data while upgrading to HFS+. The 68040 systems do not support booting from HFS+ disks; the boot drive must be HFS.
Mac OS 8.1 was the first system to have a Universal Disk Format (UDF) driver,DVD support on the Mac for the first time. It also shipped with the new Java runtime (JDK 1.13).
Mac OS 8.1 also included an enhanced version of PC Exchange, allowing Macintosh users to see the long file names (up to 255 characters) on files that were created on PCs running Microsoft Windows, and supporting FAT32.
Mac OS 8.1 is the earliest version of the Mac OS that can run Carbon applications. Carbon support requires a PowerPC processor and installation of the CarbonLib software from Apple"s website; it is not a standard component of Mac OS 8.1. Applications needing later versions of CarbonLib will not run on Mac OS 8.1. More recent versions of CarbonLib require Mac OS 8.6.
Released October 17, 1998, Mac OS 8.5 was the first version of the Mac OS to run solely on Macs equipped with a PowerPC processor. If Mac OS 8.5 is installed on a 68k system, the Sad Mac error screen will appear. As such, it replaced some, but not all, of the 680x0 code with PowerPC code, improving system performance by relying less on 680x0 emulation.
Mac OS 8.5 includes several performance improvements. Copying files over a network was faster than prior versions and Apple advertised it as being "faster than Windows NT".AppleScript was also rewritten to use only PowerPC code, which improved AppleScript execution speed significantly.
Font Smoothing, system-wide antialiasing for type was also introduced. The HTML format for online help, first adopted by the Finder"s Info Center in Mac OS 8, was now used throughout. This made it easier for software companies to write online help systems. The PPP control panel was removed and replaced with Remote Access, which provides the same functionality but also allows connections to AppleTalk Remote Access (ARA) servers.
The installation process was simplified considerably in Mac OS 8.5. In earlier versions the installer worked in segments and often required a user to click to continue in between stages of the installation. This was a holdover from the days when the OS was distributed on multiple floppy disks, disk swapping promoting a natural segmentation model. The Mac OS 8.5 installer generally required very little user interaction once it was started. Customisation options were also much more detailed yet simpler to manage.
Mac OS 8.5 was the first version of the Mac OS to support themes, or skins, which could change the default Apple Platinum look of the Mac OS to "Gizmo" or "HiTech" themes. This radical changing of the computer"s appearance was removed at the last minute, and appeared only in beta versions, though users could still make (and share) their own themes and use them with the OS. The Appearance control panel was also updated to support proportional scroll bars, and added the option for both scroll arrows to be placed at the bottom of a scroll bar.
Released May 10, 1999, Mac OS 8.6 added support to the Mac OS nanokernel to handle preemptive tasks via the Multiprocessing Services 2.x and later developer API. This update improved PowerBook battery life and added Sherlock 2.1. This free update for Mac users running 8.5 and 8.5.1 was faster and much more stable than either version of 8.5.x and was also the first version of Mac OS to display the version number as part of the startup screen. However, there was still no process separation; the system still used cooperative multitasking between processes, and even a process that is Multiprocessing Services-aware still had a portion that ran in the "blue task", which also ran all programs that were unaware of it, and was the only task that could run 68k code.
"Where do you want to pirate today?". Forbes. August 8, 1997. In fact, the latest word out in the Macwarez scene is that pirates shouldn"t copy Apple"s OS 8—Mac"s latest operating system—they should buy it, since Apple so desperately needs the money.
MacintoshPi is a small project that allows running full-screen versions of Apple"s Mac OS 7, Mac OS 8 and Mac OS 9 with sound, active Internet connection and modem emulation under Raspberry Pi. All this without the X.org manager, only a multimedia SDL2 library and from the CLI / Raspberry Pi OS Lite. This lets emulators use full power of Raspberry Pi, making them more stable and useful in combination with additional retro-software. Installation requires running a single script on a clean Raspberry Pi OS Lite and waiting about two hours for the packages to compile and install. In addition, thanks to a document contained in the project, it is possible in dual-boot to place the fastest (bare-metal) Commodore 64/128/PET emulator BMC64, thus building an interesting retro package on a single SD card. The entire MacintoshPi project runs on Raspberry Pi Zero W, Zero 2 W, 2, 2B, 3, 3B, 3A+, 3B+ (at present, it does not run on version 4).
Installation of the entire MacintoshPi package requires running the single command ./build_all.sh - all dependencies and required packages will be installed automatically:
The script downloads all files required to start Mac OS - ROMs, system images, and creates configuration files. On installation, directory /home/pi/Downloads will be visible on the Apple desktop as a Unix directory - files can be copied both ways between those two resources, but applications cannot be launched directly from that directory. In addition, the so-called NetDriver is also compiled, which allows full online access from virtualised Apple systems.
Up till now, Mac OS 9 in the full screen mode (without the unnecessary window manager) has not been available for Raspberry Pi. This is perhaps the first such implementation which allows using Mac OS 9 and SDL2 in the full screen mode with sound and online connection - even on the small Raspberry Pi 2W.
Basilisk II and SheepShaver emulators can be stopped by using the key combination CTRL+SHIFT+ESC. This causes an immediate return to the command line. The COMMAND key is acquired with the left ALT key in Mac OS 9, and with the CTRL key in Mac OS 7 and Mac OS 8.
The MacintoshPi Virtual Modem is controlled by systemd and uses the tpcser software which, through the tty0tty project, writes to virtual device /dev/tnt0. The data can be read from another virtual device /dev/tnt1, which thus becomes a virtual serial port in the system. The modem launches by default after the system boots.
It is no longer necessary to copy .toast files to the disk image or mount them with software for Mac OS - you can now unpack a .sit file under Raspberry Pi OS using the unar command, and then mount the unpacked .toast file also under Raspberry Pi OS using the cdload command, and use the CD image on any Mac OS as you would from a regular CD-ROM. Audio CDs launched in CDEmu run correctly in Raspberry Pi OS both in the graphic and text mode, but sound does not work in the Basilisk II or SheepShaver emulators. For more information about CDEmu visit the project"s website.
The maximum emulator performance is achieved in the native resolution of the emulated system, i.e. it is recommended that Raspberry Pi should start in e.g. 640x480 resolution if we want to launch Mac OS in 640x480 resolution on it.
The launcher"s task is to launch a given version of Mac OS, and if one is already running with appropriate parameters, then to overwrite config.txt and any other system files with the appropriate screen resolution and position assigned to a specific system or any other defined application, and then to launch the emulator or application right after a system restart, this time in the new resolution.
The name of the directory with the data with which the system is to be overwritten is identical as the name of the parameter following the mac command, e.g. mac os8-480 will restart Raspberry Pi OS in 640x480 resolution, and then launch Mac OS 8 also in that resolution, but the mac os8 command will simply launch Mac OS 8 in the most recently selected resolution.
Various startup chimes are played at the launch of each system - depending on the selected resolution: Macintosh 128K, Macintosh Classic II, Macintosh Color Classic, Macintosh Performa 520, Power Macintosh 550, Power Macintosh G3 sounds.
It is currently the best application for connecting with modern-day BBSs using the telnet protocol. It is compiled with options which use the SDL graphic library, thanks to which it uses a wide selection of appropriately adapted fonts in the graphic mode rather than system fonts. Again, SyncTERM does not require X.org to run, and the program itself launches in the full screen mode by default.
These websites can be used comfortably in the Chromium browser directly in Raspberry Pi OS - downloaded files are saved by default in directory /home/pi/Downloads, which is configured as a shared directory for all Mac OSs contained in this project - under Mac OS, it is displayed as a Unix drive.
unpack the file under Raspberry Pi OS using the unar file.sit command; remove any spaces from the name of the unpacked .toast file (if there are any), and then mount the .toast file using the cdload file.toast command. Next, launch a given Mac OS version and install the software from the virtual CD drive that will be displayed on the desktop.
first download an image of Stuffit Expander app and install this software in Mac OS; next, take the .sit file proper originally downloaded to the Downloads directory and copy it, already in Mac OS, from the Unix directory to the Macintosh HD virtual drive and double click the file to unpack it directly in Mac OS.
My version of MacintoshPi is driven by Raspberry Pi 3B+. I bought my Macintosh Classic II case on eBay - it was completely yellow, but I restored it to the factory condition by means of 18% hydrogen peroxide and appropriate light exposure.
Its LCD IPS 10.1’’ 1024x600px HDMI Waveshare 11870 screen is turned 180°, so that the wiring does not interfere with the upper Macintosh frame. I filled up the space between the flat screen and what was left of the CRT shape with a 3D printout designed by the authors of the 2GuysTek YouTube channel. The Waveshare screen is a bit too wide, but appropriate operation of the config.txt file allows software rotation and precise definition of the displayed screen image for each system or application (after a restart). The screen is also too low, which is why I filled up the void with black cardstock, and so those elements are practically indistinguishable (they look like the black background of the frame surrounding the screen). However, I recommend using a different, slightly larger screen, and then use software to reduce the screen image displayed and establish its appropriate position.
The keyboard and mouse are Logiteh MK295 Silent Wireless Combo - they only slightly similar in style to peripheral devices supplied back in the day, but they are also wireless and use a single bluetooth dongle. I added two speakers connected to a Raspberry Pi 3B+ analogue audio/jack input and to a splitter. I integrated all those elements inside the Apple Macintosh Classic II case.
Since the passing of Apple"s founder, Steve Jobs, in 2011, vintage Macintosh computers are finally seeing a resurgence in popularity. For those of you who decided to keep your old Macs, this is good news for you! Now these charming old machines are fetching a decent penny on eBay and Craigslist.
These often surface on eBay. These are either the "Replica 1" from Briel Computer or the Newton NTI clone. The value for an unassembled replica hovers around $1,000 for the kit.Regarding Apple/Macintosh "Clones"
During the brief and unsuccessful Apple cloning years, a number of machines emerged using licensed hardware and software. Most were inferior in both performance and quality. Today, their value is difficult to ascertain, as no two clones were truly identical. Many are considered undesirable and sell for just a few hundred dollars, if that.
Named after Steve Jobs" daughter, Lisa, this was one of the final models released before the introduction of Macintosh in 1984. Aimed at corporations, the computer"s hefty price tag of $10,000 in 1984 was considered too great a risk to take, and sales were poor. In 1986, the Lisa was renamed the Macintosh XL and fitted with an emulator to run Mac OS.
Released in January 1984 as the very first Macintosh, the 128k was the first personal computer to feature a Graphic User Interface, a basic feature that would define home computing for decades to come. The 128k was also the first to feature a 3.5" floppy disk drive.
Apple"s first expandable Macintosh, the Plus, introduced the SCSI port to allow for a multitude of external additions. It was sold to academia as the Mac ED.
Released alongside the Mac II, expansion was the primary capability of the SE series. Its new, updated case came with an expansion slot for either a second internal floppy or hard drive.
Built to replace the SE/30, the Classic II was the last of the Black & White Compact Macs. Whopping fast at 16 MHz with an 80 Mb hard drive and 10 Mb of RAM. It was also the last model to include an external drive port.
Apple"s bottom-rung inaugural Powerbook, released in 1991, would become the foundation of all Macbooks over the next 20 years. This particular model lacked CPU, RAM, and expansions that its two running mates had including a floppy drive. It has since been named the 10th greatest personal computer of all time.
A multi-colored edition Powerbook 170, the JLPGA was built as a commemorative for the 1992 JLPGA Golf Tournament in Japan. Underneath the flashy facade were the workings of a basic Powerbook 170. It was never intended to be a powerful machine but what makes it valuable is that only 500 were ever produced.
Apple"s first color compact Macintosh, the Color Classic ultimately set the stage for the iMac. Essentially a Performa platform computer inside a retro Mac body, even today the Classic has a cult following not seen since the original Macintosh. Some Color Classics have been modified to include an ethernet card that can still connect to broadband networks.
Released as a limited edition in 1993, the Macintosh TV was one of the few desktops ever released in black and Apple"s first attempt at computer-television integration. Equipped with a cable TV ready tuner card and a television monitor, the TV could switch from a computer to a television set in a matter of seconds and even came with a remote control. Yet it was incapable of recording live video, only still frames. Its poor processor speed and other limitations made the unit a failure and ultimately only 10,000 were sold.
Before the Mac Mini, there was the G4 Cube, Apple"s first attempt to build a small profile desktop computer. Unfortunately, it was a flop. Its limited capabilities and uncomfortably high price tag forced the Cube into the grave after just one year. The model was unofficially replaced by the Mac Mini. Despite its failure, the Cube did gain a cult following similar to that of "80s Macs.
Nearly bankrupt, Apple"s official turnaround with the return of co-founder Steve Jobs in 1997. One of the first things he did was kill off nearly all of Apple"s unremarkable product lines. The next thing he did was begin a full rebranding of the company from a boring industrial computer developer into a pop culture staple. The first product under this new rebrand was The iMac.
The iMac was unlike any computer of the time. First, it returned to the original Macintosh design of being All-In-One. This allowed it to be priced considerably cheaper than the competition. Furthermore, the iMac was colorful and eye catching. The inaugural color was called Bondi Blue and soon 13 color combinations were available making it marketable to just about anyone. The computer was the first to feature USB slots, a connector that is still used today. The computer was a smashing success and officially turned Apple around financially.
Despite it"s pop culture status, the 1st generation iMac"s value dropped like a stone as Apple began its business strategy of releasing a new generation of the iMac every year. In fact, by the time the mid 2000s rolled around, and the release of Apple"s revolutionary OS X, you couldn"t even give the 1st iMacs away.
Nicknamed the Lamp, the Sunflower, or the Dome & Swivel, the iMac G4 was the first major redesign of the iMac. Produced from 2002 to 2004, the Lamp was the first Macintosh to ditch the CRD monitor in favor of the flatscreen. This allowed the computer to fit just about anywhere. The computer was also Apple"s OS 9 - OS X transitional model, featuring both operating systems initially. The computer was Apple"s first to pass the 1Ghz CPU speed mark.
2010, yet another milestone year for Apple with the release of the iPad. Against all predictions of certain failure, the iPad"s success ushered in the beginning of the tablet era of computing. The 1st generation iPad established screen sizing and control placement that would make up every generation since. Factory sealed units with early serials numbers can fetch a decent amount if the timing is right.
Not every vintage computer is a jackpot. Some models happen to sell better than others. A Mac 128k, for example, can fetch well over $2,000 on eBay, while its newer cousin, the 512k, will fetch only $500. Sentimental value is not the same as resale value. Dozens of listings go unsold because of a ridiculous price of, say, $10,000 for an old, unremarkable machine that has no accessories or desirables.
There are several factors to take into account when listing your vintage Mac:First is condition: Does it work? Naturally, a working computer will sell for more than a broken one.
Some computer models are actually worth more in parts. A Mac SE/30 may only fetch $100 as a complete unit but could fetch nearly $400 in parts. Certain parts are highly prized (like the internal floppy drive, the ram, etc.).
Upgrade kits are very valuable today. Different economics applied to computers in those days. The thought of buying a new computer every two years was unheard of, so the idea was that you bought it, made repairs as needed, and kept it until it completely wore out. Macs were originally designed to be upgraded rather than replaced. By the late "80s, it became apparent that hardware limitations impeded upgrades and by the early "90s, Apple abolished upgrading altogether.
Research what your computer has, and it will help determine whether it is worth more as a complete unit or as a parts box. The prices contained on this page are based on successful eBay listings, not unsold listings. In other words, anyone can ask for $10,000 for a Mac Plus, but nobody"s going to pay that much for it.
Bullet Lists keep it short, sweet, and simple. Vintage computers sell really well on eBay Mobile. Write your listing, keeping that tiny cell phone screen in mind. Avoid writing paragraphs of information, as a long listing will actually deter an impulse buyer.
Remember, not every Macintosh is a jackpot. Many unremarkable models exist today worth just a few hundred dollars or less, for a multitude of reasons:The model was neither revolutionary in concept or function or just simply a filler model to build out the Apple product line. These were particularly common in the years leading up to Steve Jobs" return in 1997.
Not enough time has passed for it to be considered a worthwhile collector"s item. With the exception of the iPhone 1 and a few others, most collectible machines are at least 20 years or older.
I have an Apple laptop Macintosh PowerBook 160 in great condition with the owners manual, dial up modem, system discs carrying shoulder bag everything.
Have an Apple Macintosh Power PC 8100/80AV with serial # dated 9/20/94. I am willing to donate it if someone would want it. What do you think ? ? ? In very good condition and in working order.
I have an Apple Macintosh 512K M0001W Serial Number: F5415AUM0001W with external floppy drive, all original software and manuals, and working Apple ImageWriter II printer.
Condition: Overall excellent, like-new condition. Computer, mouse, external floppy drive, and printer all work well. Has none of the characteristic yellowing of the cases for the computer, mouse, keyboard, or printer seen with most Macs that are 35+ years old. Also have original boxes, though the one for the Mac is a little ragged, the one for ImageWriter II is in excellent shape.
I have an eMac computer and an Apple Macintosh computer bag which is in good condition. I am wondering what they are worth and how to sell them. The computer is too big to fit in this computer bag. I am not sure if the computer is working at this stage. They belonged to my partner who died recently. He loved all things Apple.
I have an eMac (all white) in essentially mint condition. It still works but does not have original packaging, keyboard or mouse. Any ideas on the value? I have seen them on eBay for $100-$300 but due to weight I wonder if shipping from Vancouver Island in Canada would be prohibitive. Any comments?
Have an IMac DV 400 MHZ SPECIAL ADDITION STILL in original box. Good condition on box. Not perfect on box. Looking for help on value and selling this. Thx. kvandright@yahoo.com
This is a great article. What do you envisage for computers built during and after the 90’s? Do you see a resurgence of people collecting working Apple computers as long term investments, for instance an eMac 2004 model A1002? I imagine the lower the number of units produced the higher the value appreciation. Would these be equally as valuable for parts?
I have a PowerBook g4 laptop but it has a problem with the screen. At times everything will be covered in purplish blueish pixelated boxes that covers the screen. When I tried hooking up an external monitor, the same problem happened. Do you know a way to fix this?
I have a Macintosh SE double disk but I don"t have keyboard or cords and not sure if it works as I found it in my uncles garage when he passed away so I wanted to know how much or if it"s worth anything it"s dated at 1986 model number M5010 with 1Mbyte Ram,Two 800k Drives
Hi, I"m trying to find out how much a black Macintosh power PC 275 is worth. Can any one help or point me in the right direction for advice. All in working order with box
Did you know that if you open the 1st edition Macintosh (1984), All of the original designers have their signatures on the inside of the cover including Steve Jobs and Steve Wozniak
hi, i am cleaning house and shipping somethings back to the US from France where I was living. I have an old iBook, still works, date on back is 1999. Mac OS 9.0.4
Hi! I have a 17" MacBook Pro (Mosel No: A1297). Great condition. Works great! Still have the box. Just read that it will be discontinued and going into the Apple Vintage files this year. If it goes into the vintage category, how much do you think it would be worth?
I have a working 1986 Apple Macintosh Plus Computer with Apple Image Writer ll Printer, Keyboard, Mouse & External Drive. I am the original Owner. Excellent condition. Exact production date: October 11, 1986.
In 1982, I purchased a 128K Mac with 20Mb Internal Drive with extra 3.5 inch drive and an Imagewriter printer. I could have downloaded a 12Mb? song, only. My current iMac with 1 Terabyte internal drive can download 129,720 songs, some Classical ones @ 44Mb. I sold it to a friend for $2,000 Aussie dollars because I had paid $5,200 for it in mid-1982. What"s it"s value, working.
I have a Color Classic that has a motherboard with a power PC 603 in it, maybe from a power Mac 5200. I was wondering if that would increase the value and what you think I should ask for it. Also I don"t have a working mouse for it, is there anyway to open system information with the keyboard?
I really don"t know what kind of imac it is but I am pretty sure its a imac G3. How much do you think it"s worth? It works and it has the og keyboard.
I am looking to sell Perfect Condition Macintosh IIVX 8/230 w/512k, Extended Keyboard, Personal Laserwriter NTR and 21" Precision Color Display. All purchased 8/93. Used 10 times. Stored since.
Hi Jason, I have a working, near mint condition Mac SE20 (I believe it is SE20, purchased in a college book store in 1988ish) in the original box (very clean and great condition but some clear packing tapes on and address written on 1 or 2 sides) with an unopened and an opened sets of manuals (happen to have 2 sets of same manuals) in mint conditions, plus a mouse cover shaped like a mouse which was sold in Apple "Company Store" in 1988 (no tag). Could you give me quotes for these?
I have a working Performa and a G4 (quicksilver) plus 80"s mac software...what do you think they"re worth? And does anyone know who buys old software like this? Thnaks
My father has a complete system, Macintosh 1mb with external floppy (I believe, but will check) and a LaserWriter printer. I haven"t seen any posts that mention the LaserWriter. Is the LaserWriter of any value? Is the system worth anything?
I’ve started getting into usingFPGAs. They’re really cool because when you use them you’re essentially creating hardware by typing. When you code in a hardware description language like VHDL or Verilog, you’re not writing code that a microcontroller or other processor will execute, you’re actually coding the processor itself, the actual layout of logic gates and connections between them. I had seen an example of driving an VGA monitor with an FPGA to show a pattern on the screen. I decided to see if I could do the same with a Macintosh Classic CRT and maybe push it further.
With this info I was able to write some VHDL to drive the Mac Classic’s CRT. Only 4 wires are needed, GND, VSYNC, HSYNC, and VIDOUT. As luck would have it, 3.3V is enough to trigger a logic high on this connector so I was able jump the wires straight to headers on my FPGA. I used a Mojo FPGA for this project but others should also work fine.
This was an awesome starting point, I only now had to connect to my USB to Serial cable, pack up the data and send it over. You’ll notice that the frames show with a second or so delay in-between. This is the time it takes to send all the bytes over serial. The FPGA is still clocking out frames at the CRT’s 60 fps, even as the data is slowly coming in. I could have dumped the data to a second buffer off-screen, then switched over only when all the data is sent, but I kinda like watching it as it comes in(good for initial debugging also). This does highlight another cool thing about FPGAs, you can set up as many concurrent processes as you can fit in the available gates on your chip. One could setup multiple video sources and outputs all going at the same time running off the same FPGA chip if they wanted.
-Working with these CRTs can be dangerous(hence the “High Voltage” labels). So I don’t advise anyone to play with CRT connections unless they know what they are doing. On the really old Macs, they’ll hold their charge a long time even after being unplugged. That said, this project doesn’t involve the HV connections, and can be done in a safe manner if you’re careful. Last warning on this note, be careful of where your hand will jerk as you work a connection free. To pull that connector free don’t set yourself up such that when it gives, your hand flies up and hits the CRT.
