# Interdata Simulator Configuration

Interdata was founded in the mid 1960's. It produced a family of 16b minicomputers loosely modeled on the IBM 360 architecture. Microprogramming allowed a steady increase in the functionality of successive models.

- Interdata 3
- Interdata 4 (autoload, floating point)
- Interdata 5 (list processing, microcoded automatic I/O channel)
- Interdata 70, 74, 80
- Interdata 6/16, 7/16
- Interdata 8/16, 8/16e (double precision floating point, extended memory)

In the early 1970's, Interdata was purchased by Perkin-Elmer. In 1974, it introduced one of the first 32b minicomputers, the 7/32. Several generations of 32b systems followed:

- Interdata 7/32
- Interdata 8/32
- Perkin-Elmer 3205, 3210, 3220
- Perkin-Elmer 3250

Interdata was spun out of Perkin-Elmer as Concurrent Computer Corporation.
