The original hardware design included dual-ported VRAM as graphics memory, but due to a shortage in parts, Sony redesigned the GPU to use SGRAM instead (which could simulate dual-porting to some extent by using two banks). At the same time the GPU was upgraded to utilize smoother shading, resulting in overall better image quality compared to earlier models, which were more prone to banding;

These were followed by the SCPH-700x and SCPH-750x series, released in April 1998. They are externally identical to the SCPH-500x machines, but have internal changes made to reduce manufacturing costs (for example, the system RAM went from 4 chips to 1, and the CD controller went from 3 chips to 1). In addition, a slight change of the start-up screen was made; the diamond remains unchanged but the font used for Sony Computer and Entertainment is now consistent, making the words appear smaller than the diamond overall, and the trademark symbol (™) is now placed after "Computer Entertainment" instead of after the diamond, as it was on the earlier models. New to the SCPH-700x series was the introduction of the "Sound Scope" – light show music visualizations. These were accessible by pressing the Select button while playing any normal audio CD in the system"s CD player. While watching these visualizations, players could also add various effects like color cycling or motion blur and can save/load their memory card. These were seen on the SCPH-700x, 750x, 900x, and PS one models.

The final revision to the original PlayStation was the SCPH-900x series, released in May 1999. These had the same hardware as the SCPH-750x models, except the parallel port was removed and the size of the PCB is further reduced. The removal of the parallel port is partially due to the fact that Sony did not release an official add-on for it; it was used for cheat cartridges, and for the parallel port to defeat the regional lockouts and copy protection. The PlayStation Link Cable connection was supported by only a handful of games. The SCPH-900x was the last model to support it, as the Serial I/O port was removed on all PS one models.

There were also debugging consoles - these were generally in either blue or green cases, although there were some special production units (mostly intended for use as show demo units) that were grey, the same as the retail consoles. The debug units were designed to be as close as possible to retail consoles, so they only had 2MB of ram (the developer boards had 8MB) and had standard retail boot ROMs. The only real difference is that the CD controller was reprogrammed so that it would identify any disc that had a data track as being "licensed", rather than requiring the region code in the lead-in that was present on pressed PlayStation CDs. This was done to allow developers to burn games to CD-R for testing. A side-effect of this was that most debug consoles would also boot discs from other regions (one notable exception being the later NTSC:J debugs, which only boot Japanese titles), although this was not officially supported. Sony made specific debug consoles for each region, and the TRC (technical requirement checklist) provided by Sony for each region required testing the title on the correct debug stations.

The reason for the two different case colors was a hardware change that Sony had made fairly early in the PlayStation production cycle - the original machines were built using Rev. A (early Japan market units) or Rev. B (later Japan units, US and Europe) hardware, both using the same GPU with VRAM to store the video data. Later models used Rev. C silicon and SGRAM - although the two chipsets had very similar performance, and Rev. C was explicitly designed with compatibility in mind, they were not identical - the Rev. C version was significantly faster at doing alpha blending, and hence the PS "semitransparent" writing mode - it was also rather slow at certain screen memory block moves (basically, ones involving narrow vertical strips of the display) on top of this there were some minor hardware bugs in the older silicon that had been addressed by including workarounds for them in the libraries - the later library versions checked the GPU type at startup time and disabled the patches if they were not needed. Because this made the two machine types quite significantly different from each other, the developer had to test the title on both machines before submitting. The blue debugs (DTL-H100x, DTL-H110x) had the old silicon and the green ones (DTL-H120x) had the new silicon.

In 1997, Sony released a version of the PlayStation called the Net Yaroze. It only came via mail order and was more expensive than the regular PlayStation ($750 instead of $299 for the original PlayStation). It had a matte black finish instead of the usual gray, and most importantly, came with tools and instructions that allowed a user to be able to program PlayStation games and applications without the need for a full development unit, which was more expensive than a normal PlayStation (official development kits cost around $50,000.00 at the time). It was only available to approved video game developers, who needed to sign an agreement that they wouldn"t distribute their games to anyone else or try to reverse-engineer the hardware. The Net Yaroze lacked many of the features the full developer suite provided, lacking the on-demand support and code libraries that licensed developers had.Ridge Racer ran entirely from the system RAM (except for the streamed music tracks).regional lockout; it would play games from any territory. It would not however play CD-R discs, so it was not possible to create self-booting Yaroze games without a modified PlayStation.

The PS One (officially stylized as PS one and alternatively spelled PSOne and PSone) is a smaller, redesigned version of the original PlayStation platform.PlayStation 2.

Sony also released a version with a 5-inch LCD screen and an adaptor (though it did not have a battery: it is powered by plugging the adaptor in a main socket, or in a car). It was called the Combo pack. However, it includes a headphone jack (for headphones or other audio connection) and an AV mini jack for connecting camcorders or other devices.

The first batch of PlayStations used a KSM-440AAM laser unit whose case and all movable parts were completely made out of plastic. Over time, friction caused the plastic tray to wear out—usually unevenly. The placement of the laser unit close to the power supply accelerated wear because of the additional heat, which made the plastic even more vulnerable to friction. Eventually, the tray would become so worn that the laser no longer pointed directly at the CD and games would no longer load. Sony first addressed the problem by making the tray out of die-cast metal, and additionally also placed the laser unit farther away from the power supply on later models of the PlayStation.

Sony Computer Entertainment has released an LCD screen add-on for the PSOne, the slimmed-down version of its original PlayStation game console. The $129 high-definition screen plugs into the back of the console and allows players to take their game-playing on the road, without the need to hook up to a TV set.

Several third-party manufacturers have already released similar add-ons, all of which contribute to Sony"s plans of turning the PSOne into a portable game machine. A power adapter that plugs into a car"s cigarette lighter is set to come out early next year.

The PSone was announced by Sony on June 8th, 2000. It is about a third of the size of the original Playstation, and is compatible with PlayStation software. To use the PSone, you must have a CD that is compatible with either the Playstation or the PSone in the CD player at the top of the console. You will also need to connect a controller to one of the ports on the front of the console.

This console was released in two formats: the original PSone, and a version with an LCD screen. The LCD screen is set into the circular hatch at the top of the console that was the disk cover in the original version, while the CD player is in the same place, just set slightly deeper in the console than in the original.

The PSone was very successful, even selling better than the newer PlayStation 2 when it was released in 2000. According to PC Data, a market researcher, it accounted for 42% of game console sales one week, far above the rest of the consoles available at the time (the Sega Dreamcast, the Nintendo N64, and the PS2). It was discontinued in 2006, along with the original PlayStation.

I bought a used PS1 screen from someone recently and it didn"t come with the SCPH-121 power supply. I had a couple of extra power supplies laying around, so I thought I would try them. Both of the power supplies had to be hard wired, as the plug end as well as the barrel power connector and accompanying board were MIA. Here"s the deal.

The first power supply that I tried was rated at 7.5V output at 1A. This power supply was originally made for a Netgear 4-port hub. It powered the screen for the mostpart, but there were two very visible horizontal bands that scrolled up the screen. The two bands combined covered about 1/2 the screen in total and slightly distorted the image along with making that section black and white.

The second power supply was rated at 7.5V output at 500mah and is made by Radio Shack. When I plugged it in, the screen powered up, but was obviously not as bright. Also, there was a upwardly scrolling horizontal "area" that darkened the image as it scrolled. It didn"t distorted it like the first power supply did, but you could tell that it was there, especially on dark backgrounds (like the menu screen for Project Gotham Racing 2...I was using my Xbox to test the functionality).

I can only attribute the problems to the power supplies. The only other possibility that I can think of is that the barrel connector and/or the circuit board that the connector was attached to limited interference from the input power. The images produced really looked like some sort of EMI. Now, I can say that neither of the power supplies had a ferrite core on the end, like the actual Sony SCPH-121 has.

Could that be the problem? If so, does anyone know where I can get a SCPH-121 or even an SCPH-113 CHEAP? If I end up paying more than $15 for one, then I might as well go to my local Toys R Us store and pick up another brand new LCD screen for $20.
