A number of models of Sony 's PlayStation ( PS ) video game console were produced from 1994 to 2006. Most revisions of the PlayStation were made to fix known hardware issues or lower production costs and time, while others featured substantial external changes.
49-597: Each region has its own model number; for example, Japan received the SCPH-1000, North America received the SCPH-1001, and Europe received the SCPH-1002. The final digit in the model number is the region code of the console; many games are restricted to certain regions, and the system software displays in different languages. The PlayStation went through a number of variants during its production run, each accompanied by
98-621: A bundle set called the Combo that included the 5-inch (130 mm) LCD screen attachment (SCPH-131). Prior to the set's introduction, the LCD screen was sold separately as a separate attachment for the PS One in September 2000. The attachment featured a headphone jack alongside an AV mini jack for connecting camcorders or other devices. Units made starting late December 1995 and after began using
147-405: A change in the part number. From an external viewpoint, the most notable change was the gradual reduction in the number of external connectors from the back of the unit. This started very early on with the original Japanese launch units; the SCPH-1000, released on 3 December 1994, was the only model that had an S-Video port, which was removed on the next release. This also led to a discrepancy where
196-456: A compilation with many Net Yaroze games. A promotional disc, limited to a thousand copies and featuring a number of user-developed games, was produced by SCEE and sent to PAL-zone Yaroze owners. This disc can only be played on a Net Yaroze since it requires the access card included with the system to work. Some of these games were based on arcade classics such as Mr. Do and Puzzle Bobble , while others (e.g. Time Slip ) were illustrations of
245-441: A last time by moving to more highly integrated chips, namely the replacement of external RAM with on-chip RAM, which both reduced the parts count and allowed the use of smaller and cheaper packages by reducing the number of pins required. 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,
294-452: 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. (Dimensions are 38 mm × 193 mm × 144 mm versus 45 mm × 260 mm × 185 mm.) It was released on 7 July 2000, and went on to outsell all other consoles throughout the remainder of the year—including Sony's own PlayStation 2 . The PS One
343-497: A name or design used by Canadian public authorities is protected. Some German publications, especially dictionaries, also use a Warenzeichen grapheme, ( U+1F12E 🄮 CIRCLED WZ ), which is informative and independent of the actual protection status of the name. Use of the trademark symbol indicates an assertion that a word, image, or other sign is a trademark; it does not indicate registration or impart enhanced protections. Registered trademarks are indicated using
392-603: A novel concept. The Game Developer UK Competition, organized by Scottish Enterprise in collaboration with the Scottish Games Alliance, Sony and Edge in 1998, accepted Net Yaroze entries; the overall winner was Chris Chadwick for his game Blitter Boy – Operation: Monster Mall . An updated version of Time Slip was later released for Xbox Live Arcade in February 2011 and Windows in January 2012. Some of
441-638: A similar feature to hobbyists and amateur developers on the PlayStation 2 console. The Net Yaroze kit contains the following items: Though it lacked regional lockout, the Net Yaroze console exists in three variations: one for Japan, one for North America and one for Europe and Australia. The Europe/Australia version boots in PAL mode, while the others boot in NTSC mode. There are further differences between
490-521: A special black-colored debugging PlayStation unit, a serial cable for connecting the console to a personal computer, and a CD containing PlayStation development tools. The user has to provide a personal computer (an IBM PC compatible or Macintosh ; NEC PC-9801 was also supported in Japan) to write the computer code, compile it, and send the program to the PlayStation. The Net Yaroze was neither
539-410: 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 $ 5,000 at the time). 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. Programmers were also limited by
SECTION 10
#1732776583518588-608: A version of CodeWarrior for PlayStation was released for both Windows and Macintosh in October 1996. LightWave 3D was another consumer-level PlayStation development tool. The Net Yaroze lacks many of the features the official PlayStation Software Developers Kit provided, such as advanced hardware debugging, special software, certain libraries, and Sony's extensive technical support (including BBS and live telephone support). Dedicated Usenet groups, with access restricted to Net Yaroze members, were maintained by Sony; homepage hosting
637-509: Is a symbol to indicate that the preceding mark is a trademark , specifically an unregistered trademark . It complements the registered trademark symbol ® which is reserved for trademarks registered with an appropriate government agency. In Canada, an equivalent marque de commerce symbol, ( U+1F16A 🅪 RAISED MC SIGN ) is used in Quebec . Canada also has an official mark symbol, ⟨Ⓜ⟩ , to indicate that
686-406: Is fully compatible with all PlayStation software, but compatibility with peripherals may vary. The PS One model also had additional changes, including the removal of the parallel and serial ports from the rear of the console, and the removal of the reset button (the power button is also labeled as a reset button, but the console cannot be reset without entirely turning it off). In 2002, Sony released
735-497: The registered trademark symbol , ® , and in many jurisdictions it is unlawful or illegal to use the registered trademark symbol with a mark that has not been registered. The service mark symbol , ℠ , is used to indicate the assertion of a service mark (a trademark for the provision of services). The service mark symbol is less commonly used than the trademark sign, especially outside the United States. In recent years,
784-438: The 2 MB of total game space that the Net Yaroze allowed. The amount of space may seem small, but games like Ridge Racer ran entirely from the system RAM (except for the streamed music tracks). It was unique in that it was the only officially retailed PlayStation with no 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
833-729: The 550x series, it typically has the PU-20 motherboard, a cost-reduced and rearranged board which performs almost the same as the PU-18. SCPH-7000W : Available in Midnight Blue as a promotional item to commemorate the 10 millionth PlayStation sold, this is a Japanese-region console that has a unique BIOS based on the USA NTSC-U/C version that allowed imported games from any region to be played. Units made in August 1998 use
882-633: The GPU was upgraded to utilize smoother shading, resulting in overall better image quality compared to earlier models, which were more prone to banding; additionally, performance for transparency effects was improved, resulting in less slowdown in scenes using this effect heavily. This Rev. C hardware first appeared in late 1995 and, unlike in Japan, was not marked with a model number change in NTSC-U and PAL territories - SCPH-1001/1002 systems can have either revision, as
931-528: The Japanese kit and the others; the manuals are in Japanese, the software for Japanese PCs is included, and the discs and access card sticker have different printing. The Japanese version is sometimes unofficially referred to as DTL-3000 rather than DTL-H3000. The Net Yaroze was only available for purchase by mail order; but Sony also provided it to universities in the UK, France ( EPITA ), and Japan. Additionally,
980-520: The Net Yaroze will not play user-burned CDs, a necessary restriction in order to prevent piracy and ensure that the Yaroze program would not compete with the PlayStation's professional software development kit. This however, was not a problem for licensed developers who owned the official SDK. There are many commercial PlayStation titles (such as Devil Dice , long mistaken as a Net Yaroze game ) that can be entirely RAM-resident, and have been developed with
1029-716: The Net Yaroze, while using the CD strictly to spool Red Book audio ( CD-DA ). Sony set up an online forum where users could share their homemade games, swap programming tips, and ask questions to Sony technical support staff. Many games made by hobbyists on the Net Yaroze were released on various demo discs that came along with the Official UK PlayStation Magazine (as well as other official PlayStation magazines in PAL regions) from 1997 to 2004. The last Official UK PlayStation Magazine issue, number 108, featured

#17327765835181078-601: The PU-18 motherboard, the only batch of the 750x that doesn't benefit from sharper graphics. Most likely, this was a 700x batch being mislabled as 750x units during the transition of models. Units made in April or May 1999 often use the same case as the 900x units, covering the parallel port. Some earlier 900x units have the parallel port hidden under case with the PU-22 board, particularly on ones made in May 1999. Most likely, this
1127-515: The PU-8 motherboard, which fixed issues with dynamic lighting and color banding that units with the PU-7 motherboard had (early December 1995 unit batches and prior). Units made starting late December 1995 and after began using the PU-8 motherboard, which fixed issues with dynamic lighting and color banding that units with the PU-7 motherboard had (early December 1995 unit batches and prior). Unlike
1176-593: The SCPH-5001 on the RCA jacks and RFU power connectors were removed from the rear panel and the printed text on the back was changed to reliefs of the same. Starting with the SCPH-550x series, PAL variants had the "power" and "open" buttons changed from text to symbols, something that would later appear on the redesigned PS one. Originally, the PlayStation was supposed to have provision on Video CD support, but this feature
1225-531: 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, consumer-facing add-on for it; it was used for cheat cartridges and software development hardware, and for the parallel port to defeat the regional lockouts and copy protection . The PlayStation Link Cable connection
1274-586: 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
1323-633: The U.S. and European launch units had the same part number series (SCPH-100x) as the Japanese launch units, but had different hardware (Rev. B silicon and no S-Video port)—their technical equivalents were the Japanese SCPH-3000, so had their numbering been consistent, they would have been called SCPH-3001 and SCPH-3002. Inconsistent numbering was also used for the Net Yaroze machines, which were based on SCPH-5000 and later 1001/1002 hardware, but numbered DTL-H3000, DTL-H3001, and DTL-H3002. Also,
1372-536: The change happened between revisions of the PU-8 mainboard. The PAL region consoles from SCPH-1002 up to SCPH-5552 were different from the systems released in other regions in that they had a different menu design; a grey blocked background with square icons for the Memory Card (an icon showing a PlayStation with 2 memory cards inserted) and CD player (an icon with musical keyboards) menus. The CD player also included reverberation effects unique to those systems until
1421-414: The first models (DTL-H1000, DTL-H1001, DTL-H1002) had problems with the printf function and developers had to use another function instead. This series of machines had a reputation for CD drive problems – the original optical pickup sled (KSM-440AAM) was made of thermoplastic and placed close to the power supply, eventually leading to uneven wear that moved the laser into a position where it
1470-489: The first nor only official consumer console development kit. The PC-Engine Develo predates it, and the WonderWitch followed it. The GP32 can run user programs out of the box. Finally, many earlier consoles ( Astrocade , Famicom ) offered limited programming capabilities with BASIC dialects. Net Yaroze had no direct successors on subsequent PlayStation platforms, but Sony's Linux for PlayStation 2 and YA-BASIC offered
1519-411: 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

1568-464: 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 was more expensive than the regular PlayStation ($ 750 instead of $ 299 for the original PlayStation) and was also harder to obtain than the original PlayStation, as it only came via mail order. It had a matte black finish instead of the usual gray, and most importantly, came with tools and instructions that allowed
1617-410: 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
1666-411: The other required power rails being generated internally on the main using a mixture of regulators and DC/DC converters for the various rails. It also incorporated a slightly modified version of the menu design previously used only on PAL consoles. The later revision (still designated as SCPH-10x but with a different PM-41(2) main circuit board) was functionally identical, but reduced manufacturing cost for
1715-436: The power supply on later models of the PlayStation. Some units, particularly the early 100x models, would be unable to play FMV or music correctly, resulting in skipping or freezing. In more extreme cases the PlayStation would only work correctly when turned onto its side or upside down. Net Yaroze The Net Yaroze ( ネットやろうぜ , Netto Yarōze ) is a development kit for the PlayStation video game console . It
1764-651: The release of the PS one in 2000, which featured a slightly modified version of the BIOS. With the release of the SCPH-5000 series being produced only in Japan, it followed the same exterior design as the Japanese SCPH-3xxx series, its only differences being that it was switched to Rev. C hardware (same as late 1001/1002 units) with some upgrades to flawed components from previous models and a reduced retail price. This
1813-408: 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
1862-521: The system's developers moved into the games industry; Fatal Fantasy and Terra Incognita developer Mitsuru Kamiyama became director of the Final Fantasy Crystal Chronicles series at Square Enix. Others such as Magic Castle by Kaiga were pitched to various publishers but went unreleased until it was distributed online in 2021 by one of the original staff members. Trademark symbol The trademark symbol ™
1911-422: 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
1960-484: 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
2009-460: Was a promotion by Sony Computer Entertainment to computer programming hobbyists which launched in June 1996 in Japan and in 1997 in other countries. It was originally called "Net Yarouze", but was changed to "Net Yaroze" in late 1996. Yarōze means "Let's do it together". Conceived by PlayStation creator Ken Kutaragi and priced at around $ 750 US , the Net Yaroze (DTL-H300x) package contained

2058-441: Was a very late 750x batch having their parallel ports hidden, being mislabled as 900x units during the transition of models. The last digit of the PlayStation model number denotes the region in which it was sold: 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
2107-407: Was also provided. The access was restricted according to the kit's region of origin, which made collaboration between users in different territories impractical. The Yaroze's primary RAM was the same as the consumer's model (2 megabytes). Game code, graphics, audio samples and run-time libraries were limited to fit in the 2 MB of primary RAM, 1 MB of VRAM, and 0.5 MB of sound RAM, since
2156-511: Was followed by the first major consolidation, SCPH-550x/5001 and PAL-exclusive SCPH-5552 units, released in April 1997. This model further addressed the reliability issues with the disc drive assembly by placing the drive further away from the power supply in order to reduce heat; the chipset was also redesigned to use digital servo for focus/tracking and also to auto-calibrate the drive, as opposed to manual gain/bias calibration on earlier models. Also, shielding and PSU wiring were simplified, and from
2205-463: 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
2254-409: Was no longer parallel with the CD surface. Late KSM-440ACM drives had the sled replaced with a die-cast one with hard nylon inserts in order to address the issue. 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
2303-521: Was only included on the Asian exclusive SCPH-5903 model. 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
2352-526: Was present on pressed PlayStation CDs. This was done to allow developers to burn games to CD 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
2401-485: 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. The PS one , released on 7 July 2000, was originally based on essentially the same hardware as the SCPH-900x; the serial port was removed, the controller/memory card ports moved to the main PCB and the internal power supply replaced with an external 7.5VDC power adapter with
