The VIC-II does drive the data bus to high state, but keep in mind that it is an NMOS device. You can always let the bus perform a wired-AND between NMOS outputs. If the situation was like you described, then even moving the joystick might fry the CIA (remember, one of the joystick ports is normally an output, outputting high state). With CMOS devices this is a completely different issue. Marko
