Someone (thank you merlins ghost) sent me an article on how to build a
light pen for the commodore 64 and write programs to detect it. The
c64 has a pin on one of the joystick ports that is set up for light
pen input. However, only one of the joystick ports has the pin, so it
is not possible to plug in and simultaneously detect input from 2 or
more light pens. Since the Apple II seems more hackable than the 64, I
am wondering if it would be possible to modify the c64 light pen to
work with the Apple and plug in & detect >1 light pens simultaneously.
Thoughts?
Thanks...
