It is possible to patch the code but it will take a rather large patch file. Better off to 
rewrite the KEYIN subroutine.

Or even redo the older circuit that uses a MC68HC11E2 to convert PC PS2 scan 
codes to COCO keysrtoke values.  Since the MC68HC11E2 is discontinued, that 
makes that a bit more difficult. A PIC or and AVR could be used instead.
