I found a really tiny AT-type enclosure at Dayton, stuffed a really old Socket 7 board in it (no onboard I/O), and put two cards on the ISA riser - one multi I/O to give a parallel port for the camera, and one network card to get to the network. No video. When I was debugging it, I would leave the top off the case and stuff an ISA video card in the left-most slot (sticking inches above the horizontal ISA cards), but in operations, just I/O and network. I think I did have to hunt around a while for a board that would fit inside this tiny case and that wouldn't complain about the missing video (I'm pretty sure there was an option in the BIOS to turn off all diagnostic codes or all but video or all but video and keyboard, etc.) Not all clones had that level of granularity, but some did. -ethan -- Ethan Dicks, A-333-S Current South Pole Weather at 24-Apr-2008 at 20:40 Z South Pole Station PSC 468 Box 400 Temp -42.0 F (-41.1 C) Windchill -79.5 F (-61.9 C) APO AP 96598 Wind 20.6 kts Grid 11 Barometer 697.3 mb (9982 ft ) Ethan.Dicks at usap.gov http://penguincentral.com/penguincentral.html
