It's hard to find new 5v tht(trough hole) fuses, most that you will find are smd (surface mounted and not with legs). That's why you should get it from another board, to keep it in specs. Using one that is rated for a higher voltage will work but the over-voltage protection is gone also.

So I searched, and I wasn't able to find any motherboard that had a keyboard fuse. Even the older AT ones. What should I do?

Just following up on how you went with this issue - did you manage to fix it?

Sorry for replaying after such a long time, but I wasn't active here and I didn't have much time to work on my retro hardware.

Yes, I did manage to fix it. I just soldered a wire between the 2 connectors and it worked. I didn't find a replacement for the fuse which caused this issue, so I left it as is. It will work, but I wouldn't recommend leaving it like that.

Glad you fixed it - I replaced the fuse and that fixed it too. So far, the new fuse has not blown yet.
