The PCB arrived last saturday so I popped it in the Asteroids and it didn't work.
Seller sold it as untested but did mention it was tested succesfully in 2013...
Didn't have time to have a long look, maybe there is a problem with a bad EPROM socket.
The extra PCB is WEIRD. I showed it to Jochen and he noticed there were two wires going to the main PCB for plus and minus and the thirst wire was a look going back to the small PCB again....so how can it even do anything !?!?!?
Strange but....I'm glad as it means I can safely remove it.
Oh my ... it was only now that I realized it was him that I bought my spare NAMCO Galaxian pcb from a few weeks ago.
Same story ... "untested, but was working when stored in 2013".
Upon arrival, it had a few parts missing, and is very far from being working (clock was dead, now, upon replacing the 74107 at 1D, it has a clock, but keeps watchdogging) .. oh my.
Sorry for not jumping in here earlier, the nickname didn't ring a bell right away.
