Do any of the Sega Model 2 series CPU, Video (2 and 2A), and ROM boards have cap lists?

Semicom Wyvern Wings pcb. Really would like one that isn't overpriced to oblivion.

@Mrhide Edit: Nvm. Forgot you sold the Hang Pilot board years ago. Memory is very hazy here. At the very least you got those monitors working great.

And I also ask is it possible to replace the bulky Happ sticks in U.S. Virtual On cabs with those Sanwa sticks too.

Any progress on the eeprom dumps yet?

I have a tendency to recap power supplies too as I have seen these bulging caps on two Pacifics I recapped last year. Both are in a twin Sega Virtual On running great ever since. I also suggest replacing the adjustment pot too as those tend to go bad first. Two common signs of a bad pot are...

Man I learned some stuff ever since I replaced the ADM485 on a System 246C that wouldn't read I/O boards (and that fixed it if you're wondering). The little black component is a filter meaning one should read continuity between the two ends of a filter. It's possible to check continuity between...

I've managed to replace the tiny ADM485 IC on that S246C last January but didn't have enough time to test the board then. As of last weekend, I have finally tested this board and can say this issue has been fixed. It's a small SOIC8 IC fairly near the USB connector (depending on board model) and...

Ugh. I remember making this post a few years ago. Thanks for all the info but good god my initial post is super cringe in today's standards.

A pic of the video board would greatly help since that hasn't been documented at all.

That is very nice. I also found out that the factory speakers themselves were also used in various consumer CRTs. They were also known for their poor quality in general as most owners likely resorted to buying external speakers. At some point, I may find some shielded speakers.

Not yet. They look to be manufactured in Japan and possibly the same dimensions as those Sega Blast City speakers.

Going to extend this a bit. Is it possible the OP was using a s246c motherboard because those and 256 contain an additional 5.5v .1f supercapacitor (exact same as Naomi) that isn't present in s246b and earlier. Both Time Crisis 3 board assemblies use s246c motherboards. If leakage is a concern...

Did you get this issue solved? I'm having the exact same problem with one board in a twin Time Crisis 3. Reflowing the battery socket didn't work either and I tested voltages at the socket solder points. Both boards read 3v. Thank you

I plan on updating another Ghost Squad cab soon this time using this method (the last method I used was from an RL friend's RPI). I wonder if anyone updated type 3 Triforce or Chihiro systems to the hacked media board firmware using this? I'm pretty sure it involves editing the hacked firmware...
