Can anyone out there tell me what Burroughs part numbers look like - specifically the house numbers they used for TTL and such? I have a bunch of chips with 1471-**** numbers that I strongly suspect are Burroughs ECD types, but I would like to confirm before I decide if they go to the refinery. Pickier question: Did the Burroughs mainframe people use the same house numbering scheme as the ECD people? William Donzelli aw288(a)osfn.org
