This version of the board has unpopulated provisions for a PS/2 mouse - I would like to write up a guide for implementing PS/2 mouse on this board, but there are 4 pins on the mini-keyboard controller I have yet to identify. If you have one of these please check out my thread and help me see where the last 4 pins on this keyboard controller go!
It should only take 5 minutes with a multimeter - pins 1, 2, 18 and 23. Two of them should go to pins on the 5-pin header labeled CN3 next to the keyboard DIN. One of them should connect to IRQ12 on the ISA bus.
