Recently, we picked up a second Vapor TRX to link with the one we have. We're currently going through the game, getting it cleaned up and taking care of the normal maintenance.
Although the game works, I happened to notice that the game seems to run slower than our other Vapor. The attract mode demo seems to run at a slower framerate and whatnot. I wasn't sure if it was just me going paranoid, but after looking at our other Vapor, it was noticeable.
I went through this thread, which seems to talk about the same thing.

I took a couple photos of chips to compare with the other Vapor and it certainly seems like this may be my issue.
Pics of our first (proper speed) Vapor board(s)
And pics of the second (slower) Vapor board(s)
Right now, I'm just trying to figure out what I need to do (or can do) to get this game running properly without breaking the bank. Funny thing is, there's an old Betson repair work order tag at the bottom of the cabinet. Makes me wonder if they replaced the original PCB with one containing the slower chip(s).
Thoughts/suggestions?
Thanks fellas
