Oh! I forgot about that. I should have remembered the long discussion
about binary math in 1st quarter 1100 assembler.

During the space race plus early Army missile development they built
Research Institute (now Von Braun Hall) where Sperry set up a trio
of 1108 systems. When Sperry got out of the time sharing business due
to some court decision, the Army took one, NASA took one, and UAH got
one. Not sure if the 1108 was donated but the building was and became
home to UAH school of engineering. The 1108 memory was upgraded from
core to semiconductor which I think makes it an 1100/10. That's how
we got stuck with Univac.
