Hi,

I recently purchased an old P60 that came without a keyboard. After some searching, I figured out that the motherboard is one of these: http://ohwc.narod.ru/man-dat/mainboards/intel … ans_revenge.pdf, and requires an AT (5 pin DIN style) keyboard. I have tried two PS/2 keyboards with a PS2->AT adapter, and one TurboTrax AT keyboard, but no matter what I do, the computer doesn't get past POST saying "Keyboard not detected". The only other problem is that the BIOS battery is obviously well past is due date.

There are no out-of-the-ordinary beeps from the computer when it's booting, and everything else looks fine. It's counting the memory and detecting drives, it's just not recognizing the keyboard.

When powering on the computer, there's a short flash in the Numlock, capslock and scrollock LEDs on the keyboard, but after that it's completely dead.

I've tried: unplugging and replugging the keyboard while the computer is on, jiggling the keyboard plug in the port to see if there are any contact errors, cleaning the area around the keyboard port and the nearby chips with IPA, etc. Nothing seems to work. The keyboard plug looks fine and there's contact between the pins on the plug and the solder points on the motherboard.

At this point I'm wondering if I've just been really unlucky with the keyboards I've found, or if maybe the keyboard controller on the board is broken?
