Well I don’t have a photo, but my first computer was an IBM 709. My next computer, for a very short time, was a CDC 3400, which was soon after replaced by the CDC 6400 that served for roughly 7 years as “my” mainframe. Me and many other researchers, of course.
Because of my job, and my grad school research, I had privileged access to this computer, and pretty much “run of the farm” after midnight many nights and on weekends, along with the crew who programmed “Chess 1.0” and other delicious software at Northwestern University. Our sponsor, Ben Mittman, was Director of the computer center. Once we had dial-up (“modem” look it up!) computer terminal access, my nights were spent more via remote access, but this computer still has a special meaning for me.
