Re: [M100] Joystick for the M100

As Steve mentioned, the M100 parallel port is non-standard. It has output buffers with series resistors on all of the data output pins. This means they cannot be used for either input or for any meanigful power harvesting. For input, there are only 2 signals, BUSY and BUSY_N. Each of these

[M100] Joystick for the M100

If I ever find one of these for a decent price again, I am thinking it might be neat to hack one of these on to the M100. Probably need to tap into the keyboard matrix. Anyone else do something similar to get a more intuitive use of the arrow keys?
