I found with google that it's PEEKing &HFF60 for the x-value, &HFF61 for y-value and &HFF62 for the pen status. This would mean the X-Pad won't work unpatched with a CoCo3 like the CoCoMax Pak. Anyone out there who patched it to work with a CoCo3? (I once read there's a way to patch the Max Pak for CoCo3 usage to a different address space) Torsten
