Namco System 12: repair, preservation, multi?

Hellooo @chacal231077,

.. and that's exactly what happened :)
it worked for a while,
now I was testing again as I replaced the battery with a battery holder and it stopped working..

Luckily I have another one, but it is a different revision.. so motherboard and daughter are different (only the cpu board is interchangeable),
and if I use this other known working daughterboard with the compromised motherboard it boots (even though the game is glitchy, characters don't get rendered! only the environment.)..
I figured there was something wrong with the daughterboard then, but wasn't sure what..
I started reflowing some of those little chips, but still no luck.

I'll try the connector pins as you suggested.

Thanks for the help!!
 
quick update,
I found a way to fix my issue in this other thread which I already replied to.

In short, I added IPA to the connectors and pressed the 2 boards together!
 
I'm sorry I have to focus on life changing things on the personal side and will probably be away from the hobby in the coming months.
All good mate, hopefully it's not too bad (or on the flip side that it is exciting, depending on whether it's good or bad things happening) :)
