There is a DEC system module (PDP-1/4/5/6 era) in this lot, as well as several Control Data modules of the sort used in the 1604 and 160A. These are nice display pieces, but I'm well-stocked on both accounts, so I'm going to pass on this one. With 6 hours to go, the price is at $5 with no bids. --Bill http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270315494162 Lot of 8 Vintage Circuit Boards - 1960s
