Can anyone send me a true way to convert a SEGA phaser or an NES Light >gun to work on my ATARI 7800? Yup. The 26/52/7800 FAQ tells how to do it through internal modifications to the SMS gun. A few weeks ago, I posted this simple external adapter that requires no modifications to any hardware. Only needs 9-pin male and female connectors and a 7404 inverter. 7800 port SMS gun --------- ------- pin 6-----------------------------pin 7 pin 7 (+5V)-----------------------pin 5 pin 8 (GND)-----------------------pin 8 +---------------------pin 6 | pin 1----------+ | | +5V | | _|__|__|_____________ |14 13 12 11 10 9 8 | |> 7404 | |_1__2__3__4__5__6__7_| | GND
