SAGE.
At mitre.org it says:
-When complete, the AN/FSQ-7 weighed 250 tons, and required a 3,000kW
-power supply and over 49,000 vacuum tubes. When SAGE became fully
-operational, it relied on 24 AN/FSQ-7s; they remained in service
-until the Air Force ended the SAGE program in 1983.
Is this TRUE? Did they actually use vacuum tube computers up untill 1983?
You betchum. I worked on the one at McChord AFB (25AD) from January
until August of 1983. It was shut down shortly after that. Even more
amazing, it was still doing the job up until the end. By using both
active and standby system, we had the ability to cover the airspace from
California up to British Columbia.
