Started out on a UNIVAC 1283 in 1972.
My boss came from ‘the model railroad club’ at MIT and had helped develop first burrough’s computer.
When we got our first ‘key to tape’ unti, we thought it was buck rogers time.
Wondering here now if the Space Shuttle Mission Simulator at Johnson Space Center still runs on UNIVACs and Perkin Elmer 3250's(???)
One of the BUNCH. :-)
