Error code 50 is a problem with the keyboard 6522 VIA chip. I would start there by re-seating the chip. Make sure the chip is firmly seated in the socket. I had one I/O board where the chip would practically fall out of the socket. Failing that, you can try swapping the two VIA chips on the board. (The other is for the parallel port) If the problem follows the chip (i.e. you get an error code 51) then you know the chip is bad.

A listing of the error codes can be found in the following document:
