NES Zapper Light Gun discoveries...Yet!

Posted by Reg on 4, 2001 at 9:09 PM:

Hi,

I have done some test with a NES Zapper Light Gun tonight here are the preliminary results:

1. here is the Pinout for NES gamepads:

     +----------> (purple)
     |  +-------> (blue)
     |  |  +----> Power + 5V (white)
     |  |  |
 5 +---------+  7
   | x  x  o   \ 
   | o  o  o  o |
 4 +------------+ 1
     |  |  |  |
     |  |  |  +-> Ground (brown)
     |  |  +----> Clock  (NC)
     |  +-------> Latch  (NC)
     +----------> Data   (NC)

NC -> Not connected...

The Zapper have a white wire to Pin 7 (+5V),
a brown wire to the Pin 1 (Ground), a blue wire that correspond to the Collector of a transistor (Pin 6), a purple wire (Pin 5).

When I test with a multimeter one the +5V and black wire of the multimeter on the blue wire, the power drop from +5v to 4.5V each time I point the gun to a TV and trigger the switch on the gun...

I have tried to cover the gun or point it to a light but the result seem to be achieved only when the gun is pointed to a TV!

I have a friend that have an oscilloscope so my goal is to test it out before Christmas...

2. I have scanned both sided of the pcb board of the Zapper...

thanks
