MSX2
MSX is a standardized home computer architecture, announced by Microsoft and ASCII Corporation on June 16, 1983. 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. 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. MSX systems were popular in Japan and several other countries. Eventually, 9 million MSX units were sold worldwide, including in Japan alone. Despite Microsoft's involvement, few MSX-based machines were released in the United States. The very first commercial MSX for the public was a Mitsubishi ML-8000, released on October 21, 1983, thus marking its official "release date". The meaning of the acronym MSX remains a matter of debate. In 2001, Kazuhiko Nishi recalled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yamaha V9938
The Yamaha V9938 is a video display processor (VDP) used on the MSX2 home computer, as well as on the Geneve 9640 enhanced TI-99/4A clone and the Tatung Einstein 256. It was also used in a few MSX1 computers, in a configuration with 16kB VRAM. The Yamaha V9938, also known as MSX-Video or VDP (Video Display Processor), is the successor of the Texas Instruments TMS9918 used in the MSX1 and other systems.

Texas Instruments TMS9918
VDP TMS9918A VDP TMS9918A VDP TMS9928A The TMS9918 is a video display controller (VDC) manufactured by Texas Instruments, in manuals referenced as 'Video Display Processor' (VDP) and introduced in 1979. The TMS9918 and its variants were used in the ColecoVision, CreatiVision, Memotech MTX, MSX, NABU Personal Computer, SG-1000/ SC-3000, Spectravideo SV-318, Spectravideo SV-328, Sord M5, Tatung Einstein, Texas Instruments TI-99/4, Casio PV-2000, Coleco Adam, Hanimex Pencil II, and Tomy Tutor. The TMS9918 generates both grid-based character graphics (used to display text or background images) and sprites used for moving foreground objects. The key features of this chip are, as highlighted on a 1980 presentation by Karl Guttag (one of the designers): *256 by 192 full color pixels per screen *15 different colors and/or shades * Non-interlaced color composite video output *Direct wiring to RAS/CAS type dynamic RAMS *Automatic refresh of dynamic RAMS *General 8-bit memo ...

Spectravideo
Spectravideo International (SVI) was an American computer manufacturer and software house. It was originally called SpectraVision, a company founded by Harry Fox in 1981. The company produced video games and other software for the VIC-20 home computer, the Atari 2600 home video game console, and its CompuMate peripheral. Some of their own computers were compatible with the Microsoft MSX or the IBM PC. The company ceased operations in 1988. History SpectraVision was founded in 1981 by Harry Fox and Alex Weiss as a distributor of computer games, contracting external developers to write the software. Their main products were gaming cartridges for the Atari 2600, Colecovision and VIC-20. They also made the world's first ergonomic joystick, the QuickShot. In late 1982 the company was renamed to Spectravideo due to a naming conflict with On Command Corporation's Hotel TV system called SpectraVision. In the early 1980s, the company developed 11 games for the Atari 2600, includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilobyte
The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix '' kilo'' as 1000 (103); per this definition, one kilobyte is 1000 bytes.International Standard IEC 80000-13 Quantities and Units – Part 13: Information science and technology, International Electrotechnical Commission (2008). The internationally recommended unit symbol for the kilobyte is kB. In some areas of information technology, particularly in reference to solid-state memory capacity, ''kilobyte'' instead typically refers to 1024 (210) bytes. This arises from the prevalence of sizes that are powers of two in modern digital memory architectures, coupled with the accident that 210 differs from 103 by less than 2.5%. A kibibyte is defined by Clause 4 of IEC 80000-13 as 1024 bytes. Definitions and usage Base 10 (1000 bytes) In the International System of Units (SI) the prefix '' kilo'' means 1000 (103); therefore, one kilobyte is 1000 bytes. ...

R800 (CPU)
The R800 is the central processing unit used in the MSX Turbo-R home computer. The R800 was designed by ASCII Corporation of Japan and built by Mitsui & Co The goal was a modern and pipelined CPU binary compatible with the Z80, and therefore with MSX software, while also maintaining compatibility with older MSX Z80-based hardware. Compatibility During the development of the MSX Turbo R, ASCII Corporation considered various processors, both compatible and incompatible with the Z80, as candidates. At that time, Kazuya Kishioka , a company employee, was researching and developing an ASIC that was a high-speed version of the Z80 and largely customized for the MSX architecture. For software compatibility with older MSX software, the R800 uses the same instruction set as the Z80, with only minor but useful additions, such as 8x8-bit and 16x16-bit multiplication instructions called MULUB (8-bit), and MULUW (16-bit). Also, many of the undocumented Z80 instructions were made official, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zilog Z80
The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company's first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975. The first working samples were delivered in March 1976, and it was officially introduced on the market in July 1976. With the revenue from the Z80, the company built its own chip factories and grew to over a thousand employees over the following two years. The Zilog Z80 is a software-compatible extension and enhancement of the Intel 8080 and, like it, was mainly aimed at embedded systems. Although used in that role, the Z80 also became one of the most widely used CPUs in desktop computers and home computers from the 1970s to the mid-1980s. It was also common in military applications, musical equipment such as synthesizers (like the Roland Jupiter-8), and coin-operated arcade games of the late 1970s and early 1980s, including ''Pac-Man''.

Casio
is a Japanese multinational electronics manufacturing corporation headquartered in Shibuya, Tokyo, Japan. Its products include calculators, mobile phones, digital cameras, electronic musical instruments, and analogue and digital watches. It was founded in 1946, and in 1957 introduced the world's first entirely compact electronic calculator. It was an early digital camera innovator, and during the 1980s and 1990s, the company developed numerous affordable home electronic keyboards for musicians along with introducing the world's first mass-produced digital watches. History Casio was established as Kashio Seisakujo in April 1946 by Tadao Kashio ( 樫尾忠雄 1917–1993), an engineer specializing in fabrication technology. Kashio's first major product was the yubiwa pipe, a finger ring that would hold a cigarette, allowing the wearer to smoke the cigarette down to its nub while also leaving the wearer's hands free.
