Interdata was a company which produced a line of minicomputers. They started with 16-bit machines, and added a 32-bit line; the latter were initially upward compatible with the former. They were later the Computer Systems Division of Perkin-Elmer, Inc.
Interdata machines supported several different buses, which were generally standardized and available across the line:
- the 'Multiplexor bus', which supported programmed I/O
- the ' Selector Channel bus', which supported DMA
The 32-bit machines are somewhat famous for being the first ISA after the PDP-11 to which UNIX was moved (they were, for a short period before the arrival of the VAX, the only 32-bit minicomputer).
