A Microcircuit Computer for under $35,000 (Sperry, 1965)

It’s a 21-bit avionics machine:

Full page ad is from Air Force Magazine vol 48, Dec 1965, p27:

In production. Sperry has firm orders to deliver more than 200 microcircuit computers…

Stats: 55000 operations per second, 21 bits, 4k words of core, just 32lbs in weight. 16,700 multiplies per second, less than 250 Watt, MTBF just 6000 hours.

There’s also an all-text press clipping from August that year.
