I am unsure about the Apple //, but I have played with a light pen on the
Atari. It doesn't take more then a few lines of code to get pen results. I used
PENHorizontal and PENVertical addresses in ROM, Commodore had these also. If
Apple was kind enough to forsight such an application and put such addresses
into the ][ ROM it would an easy program. In Atari basic it is like 2 or 3
lines to get everything going, about a dozen or so in Ml.
