Anyone have any idea if this would work? My Comet was without an MPU and a system 9 board is apparently a golden unicorn. There's an 11B on the bay right now that I was looking at. I've read some posts about the system 11 board being made to work, but haven't found any info on the 11B, other than the difference may be related to the sound card. This board is in questionable condition, but would hopefully at the least be able to be refurbed.

While likely possible, I don't think it'd be worth your time. You'd have to repopulate the soundboard section, and I believe due to the differences in how the special solenoid were handled between 9 & 11, there's differences in grounds and other connector pinouts.

Figured it wouldn't be that easy. Thanks
