Thanks so much guys for the answers!
I called this guy just to bust his chops and he now says that the 3 slot was a limited edition custom cabinet from SNK. He also said that you can chain a 2 slot and a 1 slot together to make a homemade 3 slot. He said it was what the "industry insiders" called "MVS Math". I asked him how he accomplished this and he quickly said that he'd forgotten. "MVS Math"! Ha, Ha, Ha, that's the biggest crock of shit I've heard in awhile!
The really scary thing is that he actually works on arcade machines! I went over to his place and he is in the process of fixing Mario Bros, Tron, Space Invaders, Crime Fighers, Golden Axe, and Mechanized Attack (SNK). The pinball machines he had completed repairing were Last Action Hero, Batman Forever, Judge Dredd, Demolition Man, and Street Fighter 2. The guy must have at least some clue about arcade machines to have repaired all those listed above.
Mabey people like him are partly to blame for the "Great Arcade Downfall". Because if there are alot of people like him in the coin-op industry that can't be a good thing!
