It was a lower-cost version of the Compucolor, which is credited with being the first home computer system with built-in color graphics, designed to hit the home computer price points.〔(CompuColor II )〕 Unlike its predecessor, it was an "all-in-one" computer, meaning that mainboard, monitor and floppy disk drive were integrated into one case. To lower costs, the original Compucolor's custom monitor and housing was re-packaged into a standard GE 13" color television set, from which the TV-tuner controls section was removed. The machine was based on the Intel 8080 and used an SMC-supplied graphics chip (CRT5027) that provided 128 by 128 in 8 colors. The system was sold with as little as 8 KB of RAM, expandable up to 32 KB, and offered with one of three keyboards, which attached to the computer with a ribbon cable. A ROM-based BASIC was also included (apparently a knock-off, but improved version of Microsoft BASIC). The original Compucolor used an 8-track tape for storage, but this proved unreliable. In the Compucolor II, it was replaced with a 50 KB 5.25" floppy disk drive, which was placed on the right side of the screen instead of the TV-tuner controls section. The file system drivers were not changed, which resulted in the Operating System continuing to think it was interfacing with a tape drive: When a file was deleted, the files beyond that point on the disk were moved to fill the empty space, using the 4 KB portion of RAM dedicated to the video as a buffer. Most software for this computer was written by hobbyists, with some software written by third parties. Intelligent Systems Corporation created a few software titles of their of own. The most important title for the Compucolor II was probably a game called "Startrek". The predecessor Compucolor was advertised with the screen showing the game running from the 8-track tape. ==References== 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「Compucolor II」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
