JAMMA Wiring to older Audio Board Question
« on: February 06, 2014, 08:24:29 pm »
This is my 2cd post...the first one was quite an adventure.  :cry:

Well, here is my quick story/question:

I have a 1982 Time Pilot game that I am converting using a new JAMMA wiring harness. I have figured out how to wire the controls, power, and video to the existing 19" monitor, but the audio has me stumped-yes I have gone to Bob Robert's page and used search on this site.

So the question is this-how do I connect the JAMMA audio wires to the one speaker set-up in this old cabinet. It has the old factory audio board with lots of wires and ribbon cable:



Thanks,
Rob from Walpole, MA

If you are doing a JAMMA conversion you just remove that audio board, since it will be obsolete (JAMMA boards have all audio circuitry and amplifiers built in).
Connect the speaker wires (+ and -) directly to the jamma connector.

Thanks, that was so obvious, I feel like an idiot for missing it!  :)

You sure you have a Time Pilot? That audio board goes to Tri Sports.

...

Never mind, I remember now.
