Few questions on the Cps1 boards, ive never had any before but recently bought a carrier airwing and a street fighter 2 turbo Japanese version from a guy in France. Both work great.

Is there any need to do any recapping like around the sound/amp area? Think ive seen before that black pad on the back could rot the traces or maybe thats the neo geos, even though in kinda skeptical of that as ive never seen that happen on any board that i can remember neo geo and others that had similar foam pad or tape. What battery does it have? think some later versions had suicide batteries like the cps2 that im very familiar with.

I guess what I am asking here is there any bulletproofing that needs done?

Thanks

This is a huge question. There are a ton of CPS1 variations, but i'll try to answer your questions:

Debatable. Some would say yes, the caps are old, others would say no unless there are issues. I'm in the latter part.

Nope, that's just foam padding.

These ones do not. You are correct, others (king of dragons, 3 wonders, etc.) did have suicide batteries.

Debatable again. Basically the main things that fail on these boards is the CP-A01 custom on the A board (main board) or the CP-B custom on the C board (top board). Lore has it the CPS2 gained a cooling fan because of overheating issues causing failure, others argue that better manufacturing made CPS2 boards more reliable. My opinion is these chips get REALLY hot in operation, so applying an adhesive heat sync on the A-custom and 68k cpu can only help. Unfortunately these custom chips are unobtonium, so replacing the whole A or C board is the only way to fix it. Fortunately there are a ton of them in the world, but given enough time I wouldn't be surprised if we see a FPGA replacement as the chips have been reverse engineered.

Exactly what I wanted to know, thank you! I think APAR sells some adhesive heat sinks I might look into that

I think IIRC Cadillac and dinosaurs actually had the whole plastic case like a cps2 but was grey for usa and did have the suicide battery. Must if been very late cps1 maybe. I am a 3rd gen family buiss operator and was a little kid in my dads shops then or a punk kid that knew nothing just starting. Now here I am trying to bring back all the machines my dad either converted to golden tee or some other crap because thats what made money at the time. I remember when literally a fully working smash tv in a dedicated cabinet was worth 500$ at most if that. Watched him sell every pinball we had when the market was shit and trading 20 pinballs for 10 brand new pool tables Made more sense. None the less I make a lot of money on my touchtunes jukeboxes, pool tables, galaxy 3 boards, but as a hobby am spending stupid money to restore old video games we sold for dirt when they were worth nothing. Crazy. I would of never guessed pinballs would be worth 2-3k more now than what my dad paid for them originally.
