Oh man, CDS/CDC (Control Data Systems/ Control Data Corporation) is where my Dad worked. Don't know if you knew him (Ed), but he was one of the last 2-4 employees for the company. He was working up in Michigan until 1996. I still remember we took a vacation to DC and in the Smithsonian they had 2 of the machines he worked on. [Him swearing at some hardware while in a museum because it had cut him is one of my best memories. Asked him how he could tell and it had a screwdriver ding from shutting it).
