Seeking info and parts for MicroVax II BA123

Well, after all the talk about a MicroVax II BA123 on the list lately, I managed to unbury mine. It appears to be all original except for 2 hard drives that may have been added as an upgrade. All the boards match up with the DEC sticker with handwritten board numbers. It has the standard cpu board, what seems to be a 2mb ram board, a serial interface board w/ 8 ports, and the standard scsi and tape interface boards. It also has some sort of loopback board in the upper 3rd slot. Does anyone have a link to reference info on these boards? I'd like to find a pair of 8mb ram boards and a network interface for this thing, so I can put it back in service for open source software development/testing. I don't know the part numbers for these boards, so any extra info would be great. I'm also looking for the door that covers the front control panel, as this machine seems to have lost its door at some point before I rescued it. If anyone has any of these parts laying around, please drop me an email. I'm more then willing to pay shipping. I really don't think I have much of anything anyone here would want as a trade, so I'm willing to pay for the parts too if required. Another interesting tidbit about this box, it still has its inventory sticker from NASA, and it orig cost good old uncle sam $22,000+. Anyone else wonder why they didn't have it outfitted with a network interface of somesort, especially with it costing that much already? -Toth
