They all seem to have Dilog CU160's. What was the CU160? Disk, communications? My bet is the seller was once one of the Boston-area DEC used equipment dealer of the 70's/80's, who is now into Telecom instead. Let's see, in the late 80's: American Used Computer was already pass? (wasn't he in Boston?). ELI was big. Who else was there? I used to know all the names by heart. There were several who weren't as big as ELI but still worthwhile. Tim.
