Speaking of touch tablets. Does anyone know how easy/practical
it would be to connect a touch pad made for an Atari to a serial
or parallel port of another computer?

The output of these type of touch tablets is X and Y analog voltages,
(0-5v I think) which require any system that it's connected to to have
some sort of A/D converter.  Given this, connection may be relativlely
simple.  A serial or parallel port is of no use, unless an A/D converter
is connected between one and the tablet, which will require some amount
of hardware hacking.
