Matt,

Good sites! A 2 or 4-line LCD display is easy to drive from a parallel
port. LcdProc sounds quite promising! This night I got my shaft
encoder connected to the joystick "switch A & B" pins, and fired up the
state machine code to read it. Worked the first time! Easier then last
time, but then as I now recall, I had to cheat and use two analog inputs
on a 4-channel A/D interface (using a parallel port) to read the
encoder! The remainder of the interface was busy driving a stepper
motor controller IC, and reading an index from my RDF hardware.
