Gauntlet: Audio Test

May 14th, 2010 Posted in Gauntlet

I’m somewhat in a hold pattern right now as I wait on more parts (that and the Frankenputer I’ve built has a shit mobo in it, thus I need to find a replacement), so I decided I would start snipping some wires and see if I could get the stock speakers (and audio amp) working.

Luckily, there is a site called The Gauntlet Hackers, which has a bunch of information on the arcade machines, including the pinouts for all of the boards in the machine (mainboard, power supply and audio amp).  I printed them out and started snipping.  Using some leftover parts and a kludge of audio adapters, I was able to get a small MP3 player running through the speakers.

Not too bad eh?  Both speakers work, so I’ll have full stereo sound (I made sure to label which is left and which is right, to save me hassle down the road).  However I still have to figure out how I want to permanently wire the audio up on this, but my first impulse is just to use RCA jacks and run a standard 3.5mm to dual RCA cable from the PC to the cabinet.  I guess we’ll see what I decide on.
