Ok. As promissed here is how to modify a Sega light gun for use
as an Atari light gun. 

Cut off the connector on the sega gun. The wires must be soldered on
to an Atari joystick connector as follows:

     Blue wire            Pin 1 stick FWD
     Gray wire            Pin 6 trigger
     Green wire           Pin 7 +5 volts
     Black wire           Pin 8 ground

Most Atari joystick connectors don't have pin 7 because the joystick 
does not need the +5 volts. Use instead a DB9 female connector with all
9 pins wired from male to female.

Once this new connector is in place,the gun will fire when you release
the trigger. The Sega trigger is backwards from the Atari gun. 
To fix this remove the five screws holding the gun together. Find the trigger
micro switch with three connections. Wire it to the normally closed contacts
instead of the open ones.

I originally found this modification in an old issue of Antic magazine.
It was August '88 vol. 7 no.4  in an article called:

Thank you Matt for the mod. It saved a lot of time looking for an Atari
gun when I bought Crime Busters for my 130XE. I hope this helps everyone
out. Not responsible for any damages that might occur. Blame Matt instead.
