Rescued: Data General Nova Boards

Hi, I was at my local uni surplus today (UC Santa Barbara) and found, buried in a bin of random industrial parts from the chem lab, some Data General Nova boards. Here's what I found, if anyone would like to help me identify them further: These boards are 15 x 15 inches: 107-000187-12X Disk Cartridge Controller, DGC Nova 107-000007-02 DGC Nova Extender Board (quantity 2, one with gouged traces) 107-000055-03 DGC D-A Converter Scope Control Card Reader 107-000054-02 DGC General Purpose Interface 107-000151-17-16 DGC Nova Cassette I/O 107-000094-00 DG Nova Compatible Wiring Board (quantity 2) D-10632-01 Data Channel Linc Tape, CO3000N Option 008 The wiring boards look to be prototyping boards, they are half filled with soldered sockets and hand-wired components. These boards are 6.5 x 3.25 inches, and have no obvious plug connectors: 107-000008-01 DGC (no other writing, quantity 2) These look like prototyping boards also, with rows for sockets and wire wrap posts on either side. Each has different components wired up. I don't have any DG stuff, and it's unlikely I'm going to acquire one in the near future (still working on my Sun 2/120), so eventually these will go to someone else. I'll be leaving Sunday on a trip until Aug 10th, but I'll try to take some photos of the boards tomorrow or Saturday (if anyone is interested in them). Jeff
