I have a 486 motherboard here which would not detect any keyboard.
I checked everywhere for the keyboard fuse, and if I did find any fuses they checked out ok.

IIRC There was even 5v on the keyboard connector, but as a hunch I did something horrible...
I "borrowed" 5v from the AT power connector and brought it directly to the 5v pin of the keyboard connector.

So, the keyboard has worked from then on but since I can't keep it forever I'm not sure if this solution is the best one to keep around.
It is my only 486 board with real L2 cache which I was hoping to build into a dosbox and give away for free.

Are there any other things I can do, or should I just leave it be?

Oh, there is also a weird issue with cachechk on this board.
Depending on the memory timings it can report fake L2 even when I know it's real.
With the lowest timings it says it's fine, anything higher and I guess the difference isn't big enough to pass it's test.

Any thoughts on that issue?
