Spectravideo, or SVI, was a U.S. computer company founded in 1981 as "SpectraVision" by Harry Fox. They originally made video games for Atari 2600 and VIC-20. Some of their computers were MSX-compliant or IBM PC compatible. They ceased operations in 1988.〔http://www.samdal.com/svhistory.htm〕 == 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 VCS, Colecovision and Commodore 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 OnCommand's Hotel TV system called SpectraVision.〔 In the early 1980s, the company developed 11 games for the Atari 2600, including several titles of some rarity: ''Chase the Chuckwagon'', ''Mangia'' and ''Bumper Bash''.〔(【引用サイトリンク】 AtariAge - Companies - Spectravision )〕 A few of their titles were only available through the Columbia House music club.〔http://everything2.com/title/Spectravision〕 The company's first attempt at a computer was an add-on for the Atari 2600 called the Spectravideo CompuMate, with a membrane keyboard and very simple programmability. Their first real computers were the SV-318 and SV-328, released in 1983. Both were powered by a Z80 A at 3.6 MHz, but differed in the amount of RAM (SV-318 had 32KB and SV-328 had 80KB total, of which 16KB was reserved for video) and keyboard style. The main operating system, residing in ROM, was a version of Microsoft Extended BASIC, but if the computer was equipped with a floppy drive, the user had the option to boot with CP/M instead. These two computers were precedent to MSX and not fully compatible with the standard, though the changes made to their design to create MSX were minor. The system had a wide range of optional hardware, for example an adapter making it possible to run ColecoVision games on the SVI. A later version, the Spectravideo SVI-728 was made MSX compatible. SVI-738, also MSX compatible, came with a built-in 360 KB 3.5" floppy drive. The last computer produced by Spectravideo was the SVI-838 (also known as Spectravideo X'Press 16). It was a PC and MSX2 in the same device. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spectravideo」の詳細全文を読む スポンサード リンク
