MITS 8800B CPU Board

Hi, Thanks for your replies. I found the relevant information. I have an extensive inventory and can source the parts and get this poor, battered board back to its old self again. However, looking through the doco I noticed that the 8800B requires a display/control and interface boards. A question for those of you that own a MITS8800 - does it need those boards for a turnkey system? Can I plug the CPU board into the backplane and run it without the d/c and i/f cards, assuming I set up the ROM and RAM cards for the system? If not, (since I do not have the d/c and i/f cards) I'll have to try and build them from the cct diagrams I have obtained. This is do-able (but a lot of work) if I can get my hands on some blank S100 w/wrap boards, but I noticed there's a 1702 EPROM chip and I'd need to get the memory map for this chip to burn my own. Failing that, and it's all too hard and bothersome for me, is there anyone that would need a repaired 8800 CPU card for trade or anything similar? rgds river
