It might be common knowledge, but just wanted to confirm.

I have heard that a Ms Pacman PCB is actually a Pacman PCB with an auxilliary daughter card installed. Is this true?

I have several working Ms Pac CPUs so if I wanted to change them back to Pacman, what would I have to do? Just take it off? What goes in the socket when the daughter card is removed?
 
Its true, but theres also a couple of character rom swaps. If you remove the daughter PCB and leave the Ms. Pac character roms in, get ready to see some funny looking Pac-Man characters.
 
Take the z80 off of the aux board and install it in the spot where the ribbon cable is now. IIRC, you need to swap out two eproms as well.

Yeah, the only differences are the daughter board and character ROMs. Very easy to switch. Just order up a set from Bob Roberts. The board locations of the chips are 5E and 5F. You can actually play Pac-Man by just removing the Z-80 CPU and transplanting it to the socket where you remove the ribbon cable from on the main PCB. It will work that way but the ghosts on the character screen in attract mode will be made up of parts of the Midway logo and the Pac-Man character on all screens will be messed up.
