One of the sub-goodies from the recent haul is a DEC CI-750 backplane in a 5-slot frame with three modules in it, though it is marked for five. 1. L0400 2. L0101 3. L0118 * (placarded for L0100) 4. L0101 * 5. L0400 * Where the * = occupied slot. The backplane has absurdly large 5V power leads (2 ea #8) and there are four coax cables coming from slot three backplane pins, all with a side-mounted fan. That's it. Also: The Nicolet scope is a 2090-III, and although there is a small trace of some kind on the screen, it is sorta autistic. :( Now to track down docs and fix it. O Goody!! Another Project!! Cheers and Thanks for all the help... John
