larger motherboards

[frotz]

I suppose one could rig up a card cage by running some rails crossways as appropriate. Also, s100 busses tended to ring, especially when long. This can be fixed on the far end of the bus with a terminator card. It doesn't seem clear how to do this with the primary motherboard on the Altair. Perhaps could this be addressed by running the front panel wires not to a motherboard, but to another card which has proper terminator resistors?
