Tom Lyon ✅#MainframeMonday Since I'm just back from Princeton reunions, today's mainframe is the IBM 360/91 - first "super" class computer in the IBM 360 family. Princeton got theirs in 1969 and ran it for about 10 years. I worked 4 years on the beast at the PUCC - but I never got to touch it! Also pictured is the console that was saved and lit up at the LCM in Seattle - along with photos of Lee Varian, Pete Olenick, and Melinda Varian - systems programmers for the PUCC.
