What do you guys have on your test rigs? And what equipment do you have for testing? I am going to be setting up two test rigs. One for the earlier Moppet Video games and one for the later Moppet Video games. I'm using orginal harness. I was thinking of wiring up a button for the coin up as I want to be able to test everything not just video and sound.

For equipment I have a soildering iron, and a volt meter. Hope to get a rom reader and burner when I figure out which one to get.

Thanks Steven
 
You don't necessarily need two seperate rigs. I just have one test rig with a Jamma harness - then use homemade adapter cards to connect non-jamma boards.

Here's my test rig:

For a monitor, I use an old Apple computer monitor. For controls, I use a modified Sega Genesis controller. Mounted on the front panel of the rig are buttons for Coin 1, Coin 2, Start1, Start2, Test, Service and Slam. Inside the box is a PC power supply and a small speaker. There's also an isolation transformer, wired into the power sockets on the right side for testing monitors. The monitor is connected via a connector on the back - I can connect the small Apple monitor, or whatever arcade monitor I'm working on. The toggle switches on the front control power for the PSU, monitor, isolation transformer, and an aux. power socket on the back.

Thanks for the pics. The earlier Moppet games can not be run off a jamma adapter. The later ones I did build a jamma adapeter but only wired video and power. (Still have it but it looks like crap).
 
What's unusual about Moppet games that prevent them from being connected to Jamma? Did they take AC voltage directly like Pac-Man, or use funny voltages? Since I've never seen a Moppet game before, I have no knowledge of them...

No idea but Pot of Gold which is the same pinouts as the early MoppetsI was told by Mark Spaeth that a Jamma Adapter couldn't be done. I can't remember why as it's been awhile. If Mark says it can't be done 99.9999% sure it can't be done.

No, I said a PCB-based one can't be done, since it's got like 6 connectors.
