The Rainbow 100 was a microcomputer introduced by Digital Equipment Corporation (DEC) in 1982 to compete in the IBM PC market. This desktop unit had the video-terminal display circuitry from the VT102, a video monitor similar to the VT220 in a box with both Z80 and 8088 CPUs. The Rainbow 100 was a triple-boot machine: VT102 mode, CP/M mode (using the Z80), and CP/M-86 or MS-DOS mode using the 8088.
