Can someone send me the memory location to peek to read joystick input on the
VIC-20. I have built a rapid-fire joystick adaptor and would like to test it
on the VIC. I can give the schematic out if you like (it is in Amiga IFF
format). Specifically I need to detect the fire button signal. Thanks!

I have built a rapid-fire joystick adaptor and would like to test it The joystick is located in first 6522 port A which address is $9111, and the bits(0-7) you need are: 2 - joy0 3 - joy1 4 - joy2 5 - joyfire The joy4 comes from second 6522 port B in address $9120 bit 7. Don't ask which joyX is which direction.. Hmm, if the port A address doesn't work try $911F since my document is seven years old and a little bit worn.. :-( --- Anssi T.
