Can Anyone Build Jamma Adapters For These Boards...

Gorf/Wizard of Wor
Bally Sente System
MCR 2 (Tron, Satan's Hollow, etc)
Q Bert
Need to test video only. Or sound too, maybe. Will pay $$. Send me a PM if interested.
 
I made one for WoW. You'll still need the audio and video boards for that one and Gorf. Not hard to make if you have an original harness.

I've made adapters for all of them, but for all that tiem and effort that goes into making an adapter, you might as well just find games to test some of them :)

Astrocades need the video interface board, and are easier with the correct amp board (although you can work around that).

MCRs are a little sketchy to do adapters for since a standard pot/amp setup doesn't work well due to odd common-mode levels

Qbert uses a odd-ball sized connector, and you need to hook up a bunch of the test panel stuff for it to work.

Sente is just ugly :)
 
I have a bench rig for qbert. It wouldnt be bad at all if all your doing is testing the main pcb. The 30/60 connector is no problem because you can just put a couple together since they will be soldered on a fingerboard.
That being said, its too time consuming making adapters so your going to have a hard time finding someone to make one for a reasonable price.
I had one made up for Gorf a while back. Like mark said your going to need the RGB board and the amp board. That one is not too hard to make up other than obtaining the parts for it.

Ugh, like HudsonArcade said, "Sente is just ugly"...

Also, a relevant thread on this: https://forums.arcade-museum.com/showthread.php?t=304149

But I got to some crazy coding that you plug in all the pins on bally/sente pcb and the code prints out what pins they connect to on a JAMMA harness to make the adapter work a little bit easier...

Starting with the last page pg 5-1 (physical) or pg 67 (PDF) in the Bally/Sente SAC-1B schematics manual (0E19-00300-0000):

This is how the input screen looks like and what I entered in for each pin:

And this is the output screen mapping the bally/sente pcb to the JAMMA pins:

So yeah, still a major PITA and a work-in-progress...

What do you guys think?
