Lets see, i think i got the tools to dismantle this thing
But something is missing in that pic.... yes ofcouse, the pong console!
The bottom..
first glance of the guts after opening..
Nice !, a socketed AY-3-5800 (aka "pong in a chip")
The manufacuter thought "hey i need to connect that coax cable together", why not use the middle pin of the powerswitch for that
The mainboard, solderside (yes i know bad pic....)
Switches for the settings still in place, will remove those later and hardwire them to the settings i want to use..
I maybe create a jumper section instead of those bulky switches..
The inside of the controllers also carry alot of electronics.... NOT
I am a bit in doubt to use this board and hack it, i might as well take the chip out of its socket and use a schematic like this :
Is that basicly what you used Jorg ?
on the other hand, a nice hacked up original old cirquit board also has its charm...
