Key Matrix Issues

keymatrix.prg is a small program to test the keyboard matrix and the joystick ports. It works on the C64DTV and the original C64.

Known defects of the C64DTV PAL keymatrix are:

  • F7 is not working at all (although F8 works)
  • The left and right shift keys are swapped.
(Both were confirmed by Suschman 2005-11-29)

This is the keyboard mapping of an original C64 (as taken from Mapping The C64):
