Warning: Numerous sites have hosted an incorrect pinout list for Burgertime.
Burgertime and Bump n' Jump (Both DECO, both licensed by Bally/Midway) used virtually the same connectors... all but one key piece.
This linked one has the correct information for Burgertime, but is wrong for Bump n' Jump.
36 Pin Connecter
Solder Side | Parts Side
--------------------------------|-----------------------------------
+ 12 V | A | 1 | + 12 V
----------------------------|---|---|-------------------------------
+ 5 V | B | 2 | + 5 V
----------------------------|---|---|-------------------------------
GND | C | 3 | - 5 V

Pin 3 should be -5 on a BurgerTime. Pin 3 should be GND on Bump n' Jump. If a BNJ board is connected it will short your -5 to GND and either shut down or burn-out the power supply. I submitted a correction to Mike's Arcade which did update it on their site.
