Looking back at ENIAC

摘要

I was the engineer in charge of the maintenance of the ENIAC from 1951 to 1953. This is a picture of me changing vacuum tubes while troubleshooting and repairing the unit. I still have schematics of the ENIAC that we used at that time (Re: "ENIAC, world's first digital computer, turns 66"; tinyurl.com/7nzdz94).
