A while back someone was asking about converting a pre-PC-hardware Buck Hunter to Pro. They wanted a look inside a dedicated Pro or later to get an idea of how the computer is wired up. Well, I just happened to be poking around in Badger's dedicated Pro so I took some pictures.
The power supply died on this computer. A standard ATX power supply drops right in from an electrical standpoint, but doesn't physically fit inside the case. My solution is to leave the PSU sitting loose inside the cabinet and run the wires through the hole, as seen here.
The connections are, left to right: I/O comm (serial), VGA video out, security dongle, audio out...
..and the connector on the far right is interesting. Insetad of including a power supply in the cabinet, PlayMechanix opted to leech power from the PC's power supply. That is, this connector provides DC power to the cabinet, not the other way around. The pinout, top to bottom:
+12V
GND
Reset (more on this later)
+5V
GND
And the I/O board this all connects to:
Clockwise from the right: Audio in from PC, Serial comm with PC, Guns 1&2, Video out to monitor, Video in from PC, and Edge connector for everything else
The I/O board has a watchdog that connects to the reset wire on the PC power connector. If the game goes out to lunch, it puts a signal on this wire that makes a special board inside the PC short out the reset button header on the motherboard, resetting the whole system.
The edge connector has power in, ground, speaker, start button lamp control, the start button switches themselves, the reset signal, and the coin door stuff -- volume +, volume -, service, test, coin meters, coin switches, DBV pulse, and on and on.
Pretty sure the video signal is VGA. Dedicated machines have a Wells-Gardner multisync in them (either a D9400 variant or a D9800 depending on production run, ours has a D9410) so I'm not 100% sure.
If you buy the PC and the I/O board you should be able to drop the game into any cabinet you'd like if you can figure out the edge connector. If someone actually wants to do this, I can probably figure out that pinout for them.
