Interdata Simulator Configuration
</H1>
<P>
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
<LI>
Interdata 4 (autoload, floating point)
<LI>
Interdata 5 (list processing, microcoded automatic I/O channel)
<LI>
Interdata 70, 74, 80
<LI>
Interdata 6/16, 7/16
<LI>
Interdata 8/16, 8/16e (double precision floating point, extended memory)
</UL>
<P>
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
<LI>
Interdata 8/32
<LI>
Perkin-Elmer 3205, 3210, 3220
<LI>
Perkin-Elmer 3250
</UL>
<P>
Interdata was spun out of Perkin-Elmer as Concurrent Computer Corporation.
