Pac-Man version question

[jspicher]

Hello guys,

Tonight l purchased a 1980 pacman cabaret from a fellow here in town. I'd posted about the machine previously here's a shot of it for S&G's.

Needs a little TLC but all in all not a bad looking machine.
Now here's the thing; when l fired it up and tried to run a pattern l was surprised to find out that they didn't work lol.
Right when a game starts 3 of the 4 monsters immediately leave the ghost house, and behaviors are quite different.
Is there anything l can do  revert this back to the original version of pacman where the standard pacman patterns rein supreme? I guess l could purchase a new PCB if necessary but l'd like to know if there's anything that can be done with the PCB l've got here. Here's a video of a game starting up if that helps ID what version l've got here:

First post a pic of the pcb so we know it isn't a bootleg.
Second, yes, you can replace the roms on the board if the are indeed a different version.

Okay l'll post a pic of it as soon as l get a chance. I plan on gutting the maching and giving it a good cleaning this weekend so l'll update it when l have the photos! Thanks for your help.

The PCB *does* say midway manufacturing co and says pacman.

Also an update, the PCB says: Midway Manufacturing Co.  PAC-MAN A082-91375-B000
in the middle of the board if that helps identify the version.

Thanks,

Download the original manual. Maybe it's just set to the highest difficulty. If that's not the case, then you might have modified ROMs. You can revert to the correct ones by burning the regular PacMan to some EPROM chips and installing those.

Hi guys, thanks for the assitance.
I've posted the same thing over on TG and got the help l needed. There happens to be a difficulty setting that's hard soldered into the board. When connected the game skips the first two levels.

After de-soldering and restarting the game works great, and pacman is back to stock.

Thanks again guys!

PS> I need 5 194 Bulbs 14V wedge (or more) for the marquee, anyone know of a good place to find them?

Duh, autozone had the lamps...
