Interdata 7/32 and 8/32

The Model 7/32 and Model 8/32 were 32-bit minicomputers introduced by Perkin-Elmer after they acquired Interdata, Inc., in 1973. The 7/32 and 8/32 are primarily remembered for being the first 32-bit minicomputers under $10,000.

The 8/32, introduced in March 1975, was a more powerful machine than the 7/32, augmented by a number of options including the notable feature of a writable control store, allowing user-programmable microcode to be employed, a floating-point processor, and a high-speed data handling extension. It increased the memory bus width to 32 bits from 16, although it maintained a 16-bit input/output bus to utilise existing controllers and to avoid the costly process of developing "double-wide" controllers.
