U24 is an 87C52 programmable microcontroller.

I have a sound board from a Pinball Magic that I want to put into an Airborne. The manuals call out different capcom part numbers for the chip depending on which game it is in and the chip in mine has a decal that calls it "Magic Music U24 Rev1.02"

I can burn the rest of the eproms at U28-U31, but if U24 is something specific to each title I'm hosed.

Any body have any experience with swapping these boards?

My german is a little rusty but I believe this post states that all revisions of U24 work in all revisions of the capcom sound board

wow, old post.

I eventually sold the board with Airborne roms in it. I burned the roms and I don't remember if I tested it or not and then the buyer who wanted it for an airborne backed out. Put it on ebay about a year ago as-is. Never heard back from buyer.

I have swapped sound boards and rom between AB, PM, BBB, and used KP rom in AB board all without issues.
