The physical planning for power and cooling and raised floors and such to be ready for delivery would take longer than that. >W.r.t. CDC 6600 Wikipedia article does not state an exact date of the >1st shipment at all, just saying that it was in 1965. Says here late 1964. It was a huge embarassment to IBM. I imagine a large part of that was that it blew up IBM's longstanding belief that you had to make a computer really complicated to make it fast, viz. STRETCH and 360/91. https://mncomputinghistory.com/control-data-corporation/ IBM sort of came around to that with the 360/44, which implemented a scientific subset of the 360's instruction set and ran nearly as fast as a /65. It was intended for process control so they added priority interrupts and some real time I/O. -- Regards, John Levine, johnl@taugh.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly
