Intergraph 6400

A friend of mine sent me the following, and I told him I would post it to the list to see if anyone here can help him. Please contact him directly; his email address is jay(a)west.net. Thanks. Yes, if you could. A mouse would be nice too. It's an Intergraph 6400, keyboard is an 8-pin mini-DIN, mouse connector liiks like a regular 9-pin PC mouse escept the mouse has boy pins instead of girls. Alternatively if someone in the So. Cal area has one of these boat anchors (without the matching boat) and wants to get rid of it our sys admin might be willing to take it off of his hands. He's either a masochist or museum-curator-in-training... We actually got it working, can see console output on the serial port but need the keyboard and probably mouse to get it to single-user mode during the boot sequence. And if anyone has a key for the switch-lock that would be extra-sweet.
