Quoted from thedefog:Just curious as to why this would be bad. I thought gold was just about identical in conductivity. Does it alter the resistance enough to make a difference? Hoping to learn something new.
Dissimilar metals...

Nice work.
FWIW, I don't think Leon's ROM will help when one of the 6532s is holding onto the IRQ line. But since you have the 6532s socketed, that should ease troubleshooting. I shouldn't see a 6532 with the IRQ leg clipped.

Quoted from applejuice:I dont give out schematics for my boards but I offer lifetime support for owners via email for help and advice or repair services for any board
All you need to do is email me or send me a pm quoting your serial number and the problem
I'm glad you offer lifetime support, but would still appreciate some schematics.
I've had two come through for repair. I got lucky and was able to repair them.
While I have you, here are a few comments on the board.
1. I'd avoid machine pin sockets.
2. If you have to respin the board, please include the normal 40-pin TC1 socket. Without that socket, neither the GPE QS80 or Marco's ROM w/PiniTech adapter can be used.
3. Do you provide any documentation such a how to use the "Leon Test ROM" feature? I noticed there is an LED on the board.
4. It would have been nice if the ICs were numbered the same as the OEM board. Alternatively, a cross reference would work too.
Regards.

Quoted from applejuice:You don't need a TC1 socket or test adapter with our board.
With respect, I beg to differ.
I use the Great Plains Electronics QuickScan 80 as my preferred diagnostic tool. Next is Marco's test ROM in a PiniTech test fixture. Both connect to the normal 40-pin socket at TC1. For your boards, I'd need an adapter module, which I don't relish building.
Again, I'm glad your boards are available. I'm happy to support repair of them, which increases their value to your customers. The more you can do to help those of us that repair them, the better your business will be. Alternatively, if you don't help us support your product, the opposite will occur.

MarAlb ,
applejuice ,
Thanks for taking the time to add the information above. The pinball community and I certainly appreciate it.
I did the comparison and the TC1 connector layout is signal identical to the myPinballs dual .100 connector layout.
