I recently acquired a Ms. Pac-man cabinet and discovered that the aux board that is attached to the main board looks different from the standard Ms. Pac daughter card. Someone on Facebook said that this aux card is rare and was made by Midway prior to full scale production on Ms. Pac-man. Is this a bootleg or a prototype?

There were many bootleg Ms. Pac auxiliary boards made to avoid the high cost of the official Midway kit. This could be one of them.

That being said, it certainly could be a Midway prototype. Not really that valuable without prototype/alternative version ROMS but still very cool.
 
I'll buy it from you ;)

In all seriousness it's a bootleg. The board was finalized and used Midway branding already by the "Miss Pac" prototype days, even before it was named Ms. Pac.

I have a stack of them. Some work, some are missing parts. One does screwy stuff to one of the intermissions but works fine otherwise. Its a mess.

Yeah I think I have over 20 of them all tested and working just never got around to selling them. I still have a ton of project pac boards to repair as well probably why I never bothered to sell the AUX boards.
 
It a boot leg. I had one in my collection someplace. While the eproms will work in a standard PCB the proms will not..
Not true, they pals will work on a standard ms pac card. One just like that is where i got my pal images that i use repairing midway ms pac aux cards.

While your works in your machine, The one I have won't work. The pal images of the one I have are different from the standard ones..

I have around 10 or 11 Pac boards that are projects. Most are beyond my help. I might be able to scare up 2 more working ones. One of the really bad ones looks like it was ran over by a car.

I guess i should have said "In my experience". It is possible there were multiple versions of the non-solder masked boards.

Another version i have wont even work on the standard pacman board. It only works on a bootleg board.
The problem of non standard stuff is that there is no standards to them. If i recall i think it was created to attempt to skirt around the copyright issues of the day. They used an inverter to flip the prom images.

I dont think it worked cause i saw several pallet loads of them go to a certified scrap yard.
