Been there, gave up on that. The Konami LaserScope is not a light pen.
It is a ZapGun clone.  It averages the light input from about a square
inch for one frame.  Nintendo patented a scheme for doing reliable
target shooting by blanking individual targets for one screen update
and watching the ZapGun power input during that time.

You need any video card worse than a VGA.  Hook the light pen input
(Nintendo pin 6) to the card 6-pin light pen header.  You may need an
inverter in this path, I can't remember.  I could never get it to
work.  Someone claimed in private mail that they did this successfuly
with an Atari ST.
