There's not much to say, just wire up the higher address pins with pullup resistors to 5v and switch connections to ground (or vice-versa).
I have tried tons of stuff... to build one of these...
I posted like 4 forums in the tech and stuff, had some help but never really got it. Even tried this didn't get that either...
What would be really cool would be to have someone make a step by step picture tutorial on how to make these things.
Here's what i could do to help...
For someone who knows how to make these and doesn't have any supplies i could send out
a few eproms with 4 2k games or sumtin like that
some 74LS14's - i bought them to use with the 16-in-1 but never got it to work so if it would work with 4 2k games then i would send them out...
some resistors - either 1k or 10k, cant remember what i have...
I have a at least 1000 original Atari PCB boards that were striped out of cases, If they would work for it i can send some of them out too.
What do yall think?
