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

Re: [M100] Joystick for the M100

The problem with an Atari style joystick is that it uses a common ground. This means all of the keys to operate a game would need to be on the same row or column. I don't know the matrix layout of the Model T's keyboard, so it might not be possible to actually wire this to any rational control

Re: [M100] Joystick for the M100

I would think this could be done with an externally connected device and a small ‘driver’. Of course, I have never tried to do anything like this on an M100, so I have no real idea what I’m talking about. Just thinking of a driver that gets ‘hooked’ into the OS that can insert keystrokes into
