ECV cartridge port Rev #3 and Light Gun circuit

I'm on a roll here! (lol!) Something was nagging me about pin B6, B7 and B8 and after it hit me...where does the Light Gun goes ?? ARGH!! Completely forgot about it! So before i post the new revision of the cartridgge port, here's some pictures i took of the ECV Light Gun (the Light Gun also works with the Epoch System 10, System 10M2 and the Toshiba TVG-610 if you didn't knew):

Huh ?? What the.. ?! There is almost nothing inside the gun! Just a photoresistor (photosensor), two metal blades which acts like a switch (or a push button) and springs, etc...Check the picture below for a better view:

If you ever get an Epoch Cassette Vision but missing the Light Gun to play the target games for the Big Sports 12 game cartridge (or the other three Pong consoles mentioned above), then have no fear...it is so simple to do your own Light Gun. You will need a 1/8 Stereo plug, one (momentary) push-button and a Photoresistor (aka Photo Darlington). If you need a schematic, here's one i've made (the circuit inside the blue square):

 

and for last, here is the revision #3 of the ECV cartridge port which includes the missing Light Gun connections:

I hope this is the last revision but if anyone finds an error or missing an information, please let me know, that will be greatly appreciated. =)
