The amiga mouse/game ports support light pens, paddles, joysticks, mice,
and anything you want to connect (even some samplers). The amiga is after
all not a PC :-).
Sean.
p.s. the game port can even be used to output signals such as the sync
signal for a light pen.
Sean,
I know it's supported at a hardware level, but I wanted to know if the
software now supports it. According to the RKM, proportional devices are NOT
supported by the system software (i.e. gameport.device, input.device). I wanted
to know if this changed in 3.0.

Ahhhhhhh! Now I see what you mean. I don't know if the system software
uses the light pen or paddles… I've never looked.
I found out how to do it, and what I was doing wrong! When you write to potgo,
you must doit it at top of frame (WaitTOF()), then read it at the bottom of the
screen. If you don't read it twice, it will wrap around during the next
vertical retrace. Well, I guess thats the right way 😉 It's working for me so
far…
