The fact that the board seems to flip between free play, and needing coins suggests something upstream of the dips is a problem, which are two s proven goodgoing to the and then onto the bus. When you say edge connector I assume you mean the ribbon cable and sockets, rather than the actual edge connector where the control lines attach.

See other items More I have testing equipment for testing PCBs. If I bend the output leg up I can get a nice clean output from the piggybacked chip.

On the scope almost all the outputs on the TTL chips look very nasty, my logic comparator fails chip after chip after chip, but the game works fine apart from the constant coin up, it’s even playable, can’t be that much wrong with it!

Function over form I say. Select a valid country. Soldering Tips Helpful Link: Seriously tho, i have a galaga that has exhibits exactly the same fault. So the maximum current in addition to this USB can source in standard mode reliably is Feed this signal into a window comparator to set the normal operating current range of the DUT, and set a level where current is too high.
Swapping these out doesn’t solve the problem. Note that this will dtasheet up to 1A per pin into the 5V supply if fuses are not used which would be ludicrous. The item may be missing the original packaging, or in the original packaging but not sealed. Am working blind again, as I have yet to get a correctly working set I cant really rule out anything.

As winny suggests, another good idea is to add a high-side current monitor to the 60v supply. So it looks like the IO Warrior56 is likely a Cyprus microcontroller with pre-assembled firmware.
