Comment on Come for ENIAC, Stay for UNIVAC and Skeduflo

Comments

I was hoping Minnesota would be mentioned, I had an older relative that once worked for UNIVAC. I didn't realize how spread out it was.

From Wikipedia:

The UNIVAC was manufactured at Remington Rand's former Eckert-Mauchly Division plant on W Allegheny Avenue in Philadelphia, Pennsylvania.[1][9] Remington Rand also had an engineering research lab in Norwalk, Connecticut, and later bought Engineering Research Associates (ERA) in St. Paul, Minnesota. In 1953 or 1954 Remington Rand merged their Norwalk tabulating machine division, the ERA "scientific" computer division, and the UNIVAC "business" computer division into a single division under the UNIVAC name.

I'm guessing all the coolest stuff had long since happened before my relative was there.

I worked at the Roseville, MN, plant in the early 80's as a CPU designer. 100K ECL. The machine was the Integrated Scientific Processor, an attached processor that could be added to an 1100/80 system. Max configuration was 4 CPU's (model 1100/84) plus 2 ISPs. The ISP was a vector processor that had approximately the same peak performance of a CRAY-1, and higher average performance. (In part because we handled the "short vector problem" more elegantly, so the last few elements of every long vector didn't pay a time penalty for dealing with the tail end of a long vector. There were a few other architectural tweaks that contributed.)

The program was not a success. Reason 1: Oil prices came way down, so seismic data reduction and reservoir simulation markets dried up, Reason 2: Univac management was timid and slow at decision-making and starved the project. Had we been properly resourced and delivered a couple years earlier, things could have been different.

Anyway, it was a hugely fun CPU to work on.
