Anyone have the Twobits diagnostic ROM? I recently acquired a pacman cocktail with the ABC ROM board in it, but just has the fast Ms. Pac ROM installed.

While I understand these aren't great for diagnosing problems, I do already own the board so I thought it might be worth a shot on my other semi-broken pcb.
 
This is what I have on file. Not sure which is which.

I've got the ABC rom board that is "1996" with a diagnostic rom. Based on the markings, it says "converts pac to ms pac". The documentation on the site is copyright 1999. I'm just wondering about the different roms that can go in this board. It is not the kit, just a single board that connects to the 40pin z80 socket. I haven't really used it, but am starting to sort out all my pacman stuff to get some of them to work
