Rainbow 100
The Rainbow 100 was a microcomputer introduced by Digital Equipment Corporation (DEC) in 1982. This desktop unit had a monitor similar to the VT220 in a dual-CPU box with both Zilog Z80 and Intel 8088 CPUs. The Rainbow 100 was a triple-use machine: VT100 mode (industry standard dumb terminal for interacting with DEC's own VAX), 8-bit CP/M mode (using the Z80), and 16-bit CP/M-86 or MS-DOS mode using the 8088.〔 == Models ==
The Rainbow came in three models, the 100A, 100B and 100+. The "A" model was the first released, followed later by the "B" model. The most noticeable differences between the two models were the firmware and slight hardware changes. The systems were referred to with model numbers ''PC-100A'' and ''PC-100B'' respectively; later were also designated ''PC-100B2''.
