Need Help Identifying CPS1 B board

http://www.arcadecollecting.com/info/cps-b_numbers.html

I went to the above website but I can not for the life of find any model # on my CPS1 B board for my SF2. Where am I supposed to be looking for it?

I can find the PALs but not the CPS-B#

RomIdent is your freind.

Just been looking at my CPS boards and also can not ID the numbers on the list in the link.

There are numbers above the "made in Japan" in between sockets CN1 and CN2. For instance UN Squadron is # 88622B-3 but I can not find a reference list using these numbers ?

The stickers over the eprom windows are of some help.

Also the C board usually has asticker with the game name on.

I just realized that the model is on the surface mount chips.

The B board does not have smds but the C sub pcb does, that is the clue, the underside of the C board, on the smd custom IC

I thought they were interchangable, to do with the Q sound feature, but obviously not.

UN Squadron is indeed CPS-B-11 DL-0411-10004
