MSX is a standardized home computer architecture, announced by Microsoft and ASCII Corporation on June 16, 1983.[1][2] It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, then vice-president at Microsoft and director at ASCII Corporation.[3] Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines.[4][5]

MSX systems were popular in Japan and several other countries. Sony was the primary manufacturer of MSX systems at the time of release, and throughout most of the products lifespan, producing more units than any other manufacturer. Eventually 5 million MSX-based units were sold in Japan alone. Despite Microsoft's involvement, few MSX-based machines were released in the United States.[6]

The meaning of the letters M-S-X remains a matter of debate. In 2001, Kazuhiko Nishi recalled that many assumed it was derived from "Microsoft extended", referring to the built-in Microsoft Extended BASIC (MSX BASIC). Others believed it stood for "Matsushita-Sony". He said that the team's original definition was "Machines with Software eXchangeability".[7] (In 1985 he gave a conflicting definition, that he named MSX after the MX missile.[8])

Before the success of Nintendo's Family Computer, MSX was the platform for which major Japanese game studios such as Konami and Hudson Soft produced video games. The Metal Gear series, for example, was first written for MSX hardware.[9]


The Spectravideo SV-328 is the predecessor of the MSX standard. Many MSX programs were unofficially ported to the SV-328 by home programmers.

In the early 1980s, most home computers manufactured in Japan such as the NEC PC-6001 and PC-8000 series, Fujitsu's FM-7 and FM-8, and Hitachi's Basic Master featured a variant of the Microsoft BASIC interpreter integrated into their on-board ROMs. The hardware design of these computers and the various dialects of their BASICs were incompatible.[10] Other Japanese consumer electronics firms such as Panasonic, Canon, Casio, Yamaha, Pioneer, and Sanyo were searching for ways to enter the new home computer market.

Nishi proposed MSX as an attempt to create a single industry standard for home computers. Inspired by the success of VHS as a standard for video cassette recorders, many Japanese electronic manufacturers along with GoldStar, Philips and Spectravideo built and promoted MSX computers. Any piece of hardware or software with the MSX logo on it was compatible with MSX products of other manufacturers. In particular, the expansion cartridge form and function were part of the standard; any MSX expansion or game cartridge would work in any MSX computer.

Nishi's standard was built around the Spectravideo SV-328 computer.[11] The standard consisted primarily of several off-the-shelf parts; the main CPU was a 3.58 MHz Zilog Z80,[12] the Texas Instruments TMS9918 graphics chip with 16 KB of dedicated VRAM, the sound and partial I/O support was provided by the AY-3-8910 chip manufactured by General Instrument (GI), and an Intel 8255 Programmable Peripheral Interface chip was used for the parallel I/O such as the keyboard. This was a choice of components that was shared by many other home computers and games consoles of the period, such as the ColecoVision and Sega SG-1000 video game systems. To reduce overall system cost, many MSX models used a custom IC known as "MSX-Engine", which integrated glue logic, 8255 PPI, YM2149 compatible soundchip and more, sometimes even the Z80 CPU. However, almost all MSX systems used a professional keyboard instead of a chiclet keyboard, driving the price up compared to the original SV-328. Consequently, these components alongside Microsoft's MSX BASIC made the MSX a competitive, though somewhat expensive, home computer package.

The Canon V-20 has 64 KB of RAM while its little brother, the V-10, has 16 KB.

On 27 June 1983,[13] the MSX was formally announced during a press conference, and a slew of big Japanese firms declared their plans to introduce machines. The Japanese companies avoided the intensely competitive U.S. home computer market, which was in the throes of a Commodore-led price war. Only Spectravideo and Yamaha briefly marketed MSX machines in the U.S. Spectravideo's MSX enjoyed very little success, and Yamaha's CX5M model, built to interface with various types of MIDI equipment, was billed more as a digital music tool than a standard personal computer.


MSX spawned four generations. The first three, MSX (1983), MSX2 (1985),[14] and MSX2+ (1988), were all 8-bit computers based on the Z80 microprocessor.

A new MSX3 was originally scheduled to be released in 1990, but delays in the development of its Yamaha-designed VDP caused it to miss its time to market deadline.[15] In its place, the MSX TurboR was released, which used the new custom 16-bit R800 microprocessor developed by ASCII Corporation intended for the MAX3, but features such as DMA and 24-bit addressing were disabled. By the time the MSX TurboR standard was announced in 1990, only Panasonic was manufacturing MSX computers. Its initial model FS-A1ST met with moderate success, but the upgraded model FS-A1GT introduced in 1991 sold poorly due to its high retail cost of 99800 yen. Production of the TurboR ended in 1993 when Panasonic decided to focus on the release of 3DO.[citation needed] The VDP was eventually delivered in 1992, two years after its planned deadline, by which time the market had moved on. In an attempt to reduce its financial loss, Yamaha stripped nearly all V9958 compatibility and marketed the resulting V9990 E-VDP III as a video-chipset for PC VGA graphic cards, with moderate success.


The Hotbit, developed by Sharp's Epcom home computer division, was a hit in Brazil.

MSX Sakhr AX150 (صخر), made in Japan by Yamaha for the Kuwaiti company Al Alamiah, sold in Egypt and the Gulf Cooperation Council states.

In Japan, South Korea, Argentina, and Brazil, the MSX was the preeminent home computer system of the 1980s. It was also fairly popular in continental Europe, especially in the Netherlands and Spain. Classrooms full of networked Yamaha MSX computers were used for teaching informatics in schools in some Arab countries, the Soviet Union, and Cuba, where they were widely used in public schools,[16][17] which allowed the Cuban government to educate students in computer subjects In total, 9 million MSX computers were sold in Japan, making it relatively popular. However, the MSX did not become the worldwide standard envisioned because of limited adoption in other markets. Before the MSX's lack of success in these markets became apparent, US manufacturer Commodore Business Machines overhauled its product line in the early 1980s and introduced models such as the Plus/4 and Commodore 16 that were intended to better compete with the features of MSX computers.

In comparison with rival 8-bit computers, the Commodore 64 sold 16 million units worldwide in its lifetime, the Apple II sold 6 million units,[18] the ZX Spectrum over 5 million units, the Atari 8-bit sold at least 4 million units, the Amstrad CPC sold 3 million units, and the Tandy TRS-80 Model 1 sold 250,000 units.[citation needed]

A Sony MSX2 machine was launched into space on board of a Russian MIR spacecraft.[19]

Similar systemsEdit

The system MSX most closely resembled was the Spectravideo SV-328 home computer (Spectravideo even claimed to be "MSX compatible" in advertisements before the actual launch of MSX systems, but it was in fact not completely compatible with it). This led to a new and short-lived kind of software cracking: converting. Since the MSX games were unplayable on the SV-328 computer, SV-328 crackers developed a method of modifying the (MSX) games to make them work on the SV-328. In most cases this included downloading the MSX BIOS to the SV-328 from tape or floppy disk. Spectravideo later launched the SVI-728 which completely adhered to the MSX standard.

The Sega SG-1000, the Memotech MTX and the ColecoVision all have many similarities with the MSX1 standard, but none are really compatible with it. Porting games between those systems is somewhat easy. It was also very common to port games from the ZX Spectrum to the MSX, since both have the same CPU, the Spectrum 128 had the same soundchip, and the ZX Spectrum's graphic mode could be easily emulated on the MSX's screen-2 mode.


By default MSX machines have a hardcoded character set and keyboard scan code handling algorithm. While MSX has full application software compatibility at the firmware (BIOS) level, due to minor hardware differences, replacement of the BIOS with another from different PC may render incorrect scan code translations and thus incorrect behaviour of the keyboard subsystem for the application software.

In 2011 AGE Labs introduced Language Pack firmware, aiming to make each model support several localizations. By default installed into GR8BIT instead of the Kanji-ROM, it allows changing the character set and keyboard layout of the machine at startup. This allowed changing between Japanese, Russian, International and Portuguese locales, and the ability to change locales during machine operation using newly introduced BASIC command LANG.[20] Selected locale setting is stored into the unused RTC NVRAM memory space.


Several popular video game franchises were established on the MSX:

Others received various installments on the MSX, including several titles unique to the system or largely reworked versions of games on other formats:

2001 RevivalEdit

In 2001, Kazuhiko Nishi initiated a 'MSX Revival' around an official MSX emulator called MSXPLAYer. This is the only official MSX emulator as all MSX copyrights are maintained by the MSX Association. In 2004, a Dutch company Bazix announced they had become the representatives of MSX Association in Europe, being the English contact for any questions regarding the MSX trademarks, copyrights, and licensing. On October 17, 2006, Bazix launched WOOMB.Net, a website selling MSX games in English and other languages, with a selection of 14 games. In Japan, game sales began earlier, through Project EGG. WOOMB.Net was the English counterpart of this and other Japanese services offered by D4 Enterprise, which also announced in August 2006 the launch of a new MSX2 compatible system called the "one chip-MSX", a system based on an Altera Cyclone EP1C12Q240C8 FPGA.[21] The one chip-MSX" is similar in concept to the C-One, a Commodore 64 clone also built on the basis of a single FPGA chip. The new MSX system is housed in a box made out of transparent blue plastic, and can be used with a standard monitor (or TV) and a PC keyboard. It has two MSX cartridge slots and supports the audio extensions MSX-MUSIC and SCC+. A SD/MMC-flashcard can be used as an external storage medium, emulating a disk drive and can be used to boot MSX-DOS. Due to its VHDL programmable hardware, it is possible to give the device new hardware extensions simply by running a reconfiguration program under MSX-DOS. The "one chip-MSX" also has two USB connectors that can be used after adding some supporting VHDL code.

On June 7, 2008, the MSX Resource Center Foundation reported that the MSX trademark had moved from MSX Association to the MSX Licensing Corporation,[22] referring to a Benelux trademark register page of MSX, which names the MSX Licensing Corporation as entitled entity till 28-10-2013.[23] At that time, the website of the MSX Licensing Corporation that they linked to as source, had a text saying 'We are planning to revitalize MSX, the innovative computer platform.' on it. However, the website was later changed to contain only the logo of ITNY & Partners, and a link to ITNY & Partners' English and Japanese websites and has no mention of the MSX Licensing Corporation at all. On June 26, 2008, Bazix reported on their website's front page that they are no longer the representative of MSX Association, due to being unable to achieve their goals of "bringing about the commercial MSX Revival beyond the Japanese borders" and "the transfer of the MSX trademark from MSX Association to MSX Licensing Corporation" and "no outlook on any progress in the Western One Chip MSX project any time soon". As a result of this, WOOMB.Net is taken offline as well, with its website redirecting to the Bazix website, until "a solution free of MSX Association's contributions has been completed". According to their post, they will cooperate with D4 Enterprise and the MSX Licensing Corporation "in one or more retro gaming related projects".

On July 4, 2008, MSX Association's European contact website, which states to be the "only official contact place for MSX Association in Europe", reports that the MSX trademark and copyright has been under the MSX Licensing Corporation holding ever since 1983. It explains that MSX Association, chaired by Dr. Kazuhiko Nishi is the operational division of MSX Licensing Corporation which manages the trademarks, logo and copyrights for MSX. According to the same article, D4 Enterprise "refuse to pay royalties to MSX Association for the use of ESE Artists' Factory's work in 1chipMSX and the software licenses in Project Egg", thus they deal with Kazuhiko Nishi 'directly' through the MSX Licensing Corporation. The article mentions as well the ESE MSX System 3, on which the 1chipMSX (also known as One Chip MSX or OCM) is based.

On July 5, 2008, the MSX Association's Europe website posted an announcement reporting that D4 Enterprise was selling the 1chipMSX illegally.[24] In the same post it is stated that Bazix no longer is their representative in Europe, due to Bazix cutting off their relationship.

2011 RevivalEdit

Assembled GR8BIT kit

In 2011, AGE Labs announced[25] the launch of a MSX kit called GR8BIT[26] - the do-it-yourself computer for learning purposes, which was licensed by the MSX Licensing Corporation. The kit is priced at $499 and includes all necessary components to assemble a working MSX2 compatible computer, except for an ATX chassis, power supply, floppy drive, hard disk, PS/2 keyboard and monitor. It also comes with assembly and operational manuals and a supplement compiled from vendor and community support (from the "GR8BIT Engineering Community").

2014 RevivalEdit

SymbOS, an alternative operating system

Some of the Korean forum members who made Zemmix Neo created a new version of MSX called Mini IQ3000 Cutie, which has similar features to the IQ-2000 (MSX2. Made in Korea. Daewoo Electronics ) It is based on 1ChipMSX but has some special features like 'Scan Line Generator' and 'Multi Language Support'. The scan line generator generates scan lines to show the MSX screen with better quality. It supports 2 languages at the same time. Normally it shows Korean font and working as Korean version of MSX but when pressing the 'del' key while booting, it changes to Japanese mode. Even though the default mode is Korean, the default font allocation table is Japanese, as it shows Japanese characters when executing Japanese version software.[27]

The keyboard is a functionally separate unit which could be connected by non-multiplexed and multiplexed interfaces. Multiplexed keyboard units feature additional data direction line, allowing sending scan line number to the keyboard using same data lines used for return scan code, decreasing overall number of wires between keyboard and machine. Non-multiplexed interface is usually used for internal keyboards (and some external keyboards, like Panasonic CF-3300); multiplexed interface is used for external keyboards (e.g. in Yamaha YIS805 model).

The keyboard is organized as a matrix with maximum 11 input lines and 8 output lines, accounting for maximum 88 keys (including all control, numerical and alphanumerical keys). Each scan line is regularly queried to identify the state of the keys on the line; query speed is identified by the system interrupt frequency. Such organization allows system to sense state of each key, not exhibiting notorious problem with 8042 microcontroller-based keyboards when pressing several keys simultaneously (usually more than 3) generates wrong input characters, or renders inability to sense the press of more keys.

Due to the keyboard scan being controlled by the system interrupts, one of the troubleshooting hints when an MSX machine does not display any image (assuming power is present) is to press the CAPS key to see if the respective LED toggles. If it does not toggle, the system is likely suffering a more serious problem than just lack of image on the screen (i.e. the problem with video cable or video display interface in overall).

In 2009 Kamil Karimov designed the adapter board[29] to connect PS/2 keyboard to the multiplexed MSX keyboard interface. The firmware embedded into its ATTiny chip was tailored for Daewoo CPC machines.

In 2011 AGE Labs embedded a PS/2 keyboard controller unit, based on Microchip microcontroller, into its GR8BIT do-it-yourself machine. Its firmware is developed to directly convert PS/2 scan codes to the MSX keyboard scan codes. Thus it is fully transparent to the applications, allowing use of the controller unit with different MSX-compatible machines and for different localization setups.[20]


MSX standard requires at least 1 cartridge slot, most MSX models have 2. These slots[30] are interchangeable, so in most cases it makes no difference in which slot a cartridge is inserted. The physical connector is a 50 pin (2 x 25 contacts), standard 2.54 mm (0.1 inch) pitch edge connector. Using these cartridge slots, a wide variety of peripherals could be connected.

Regular game cartridges are about the size of an audio cassette (so-called "Konami size"). Despite their higher cost, this was a popular format due to its reliability and ease of use.

Around 1985, Hudson Soft released the credit card-sized Bee Card, which was meant as a cheaper and more convenient alternative to ROM cartridges. But it was a commercial failure, and very few titles were released on the format.

Source files[31] for development of the MSX cartridges are available from AGE Labs for EAGLE.

Floppy disk drivesEdit

MSX systems generally did not have a built-in disk drive, so games were published mainly on cartridge and cassette tape.[10] Sony created a battery backed RAM cartridge the HBI-55 "data cartridge" for some computers in their "Hit-Bit" line of MSX systems, that could be used to store programs or data as an alternative to cassette tapes.[32]

Floppy disk drives were available for MSX however, in the form of a cartridge containing the disk interface electronics and a BIOS extension ROM (the floppy disk drive interface), connected to an external case with the drive. In South-America, many of these systems used a 5.25 in (133 mm) floppy disk drive, but in Europe, 3.5 in (89 mm) drives were more popular. In Japan, some MSX1 systems included a built-in 3.5" disk drive, like the Panasonic (previously named Matsushita) CF-3000. In Europe, a range of Philips MSX2 systems NMS 8230, 8235, 8245, 8250 and above featured either 360 or 720 Kb 3.5" floppy drives.

In 1985, the MSX2 was released, and these systems often (but not always) included a built-in 3.5" disk drive too. Consequently the popular media for games and other software shifted to floppy disks.

The MSX-DOS disk operating system had internal software mechanisms much like CP/M (so CP/M software could be ported reasonably easily), but had a file system compatible with MS-DOS. Its user commands were also similar to early MS-DOS versions. In this way, Microsoft could promote MSX for home use while promoting MS-DOS based personal computers in office environments.[33]

The MSX 3.5" floppy disks are directly compatible with MS-DOS (although some details like file undeletion and boot sector code were different). Like MS-DOS 1, MSX disks (formatted) under MSX-DOS 1 have no support for subdirectories.[34]

In September 2012, AGE Labs extended the standard by including support for 1.44Mb 3.5” format. The 1.44Mb diskette size goes in two configurations: Standard (1 sector per cluster, 9 FAT sectors), and Compatible (4 sectors per cluster, 3 FAT sectors).[35]

MSX computers are emulated on many platforms today. Early MSX emulators were often based on the code of the pioneer fMSX, a portable MSX emulator by Marat Fayzullin. Many emulators removed Fayzullin's Z80 emulation code entirely in later versions to avoid legal problems, as at the time fMSX wasn't free software. Somewhat later fMSX source code became free for non-profit use; however a license was still required for commercial use. On December 31 2013, the Windows version of fMSX 3.7 was released, free for anyone to use.[36]

The official MSX emulator MSXPLAYer (in Japanese) is produced by the MSX Association, of which the inventor of the MSX standard, Kazuhiko Nishi, is the president.

As of version 0.146.u, MESS currently supports 90 percent of all MSX Versions.

Virtual ConsoleEdit

In February 2007, Nintendo of Japan announced that MSX games will be available for the Wii's Virtual Console emulator. It was confirmed that the games would cost 700 Wii Points and will become available from the middle of 2007. It also became available for the Wii U on December 25, 2013. Ultimately 13 games, mainly Konami titles, for the Wii plus 1 for the Wii U were released for the service in Japan only.
