Hi All, how does the C64 kernal scan the keys - does it strobe column by column (pa0 - pa7, one by one) and read the answer in pb0 - pb7; or does it set all columns at once? I'm wanting to drive something off the Joystick ports (eg a rumble-pack type device), but I want it only to respond to specific codes, not the keyscan routines. I'm hoping that I can use illegal joystick moves as a code (ie grounding left and right at the same time), but this won't work if the keyboard routine also grounds more than one line at a time. Does anyone know the answer? Regards, - Nick PLEASE TAKE NOTE: The contents of this email (including any attachments) may be privileged and confidential.
