Intelligent Systems Corp. introduced the Intercolor 3261 in 1979, one of the first desktop computers to offer a color CRT display. One drawback, it costs $9344.67 with inflation ($3300 originally).
The 13″ screen can display 32 lines of 64 ASCII characters, as well as plot graphics on a 128 x 128 grid —in eight brilliant colors. A full-featured keyboard (117 keys) and 51K mini-disk drive are built-in. as is Extended Disk BASIC, vector software and 32K user RAM. There’s a standard RS232C interface for use as a timesharing terminal, too
