I have a QBus board that I would like to identify. Its made by Digital Pathways and the model number is TCU-50 Rev A. It is a quad size board and there are three small batteries in the top right corner of the board. There are no peripheral connectors on the card, so I figure its some type of clock or possibly a small amount of battery backed up storage (the machine it was take from was used for collecting process data). Any ideas of what it might be? -- Dr. Mark Green mark(a)cs.ualberta.ca Professor (780) 492-4584 Director, Research Institute for Multimedia Systems (RIMS) Department of Computing Science (780) 492-1071 (FAX) University of Alberta, Edmonton, Alberta, T6G 2H1, Canada
