Universal Jamma Adapter - DIY??

It's pretty clever. I like the idea, but it can be dangerous for some boards that don't have that length of PCB leads. Like if you are off one or two.

I have always made mine from parts I got from Bob Roberts. You put your wires in and solder them to the cross-referenced pins and it's permanent.

This one is clever because you can modify it later for whatever you want. Screw in a wire from Pin 1 to like Pin 14 on either side. Clever.

But if you were to say have a frogger board and you didn't get it on there just right, you can shift it over a pin or two and put power where you don't need it.

If you build your own, it's a lot cheaper, but a hassle.
 
I see what you mean, I suppose that's why the seller offers one with a 44 pin connector or none at all.

They've sold 16 already, figured at least 1 forum member bought one.
 
Interesting, but I think it sucks. Terminal blocks are spaced too close to each other. There needs to be about three holes in the board between the terminal blocks in order to pass wires through from the front side to the back side of the board. Price is way too high also.

Fingerboards are much cheaper, widely available, and I like the reliability of soldering. No chance of weak, intermittent connections when they are soldered.

Might be OK for whipping together a test adaptor. But there are easier and cheaper ways to do that.

That's actually why I was considering it. I have a moon patrol, centipede, and terra cresta that I wanted to test.

As for your thoughts Ken, I agree, for permanent use it would be a little mickey mouse.

What would be an easier and cheaper way to do this?
 
I spend about $4 in parts on a fingerboard and a connector, use some spare wire I already had, and make my own adapters based on whatever board I want to test. Some adapters like Centipede will stay that way only for Centipede. Others are better because they may be compatible with lots of boards (like Taito Classic, Konami Classic, etc). Since I never know what board or when I may come across, or if a friend calls to see if I can test a board for him, I just make up a bunch of different ones as I need them and then keep them.

In your case, if you only have three boards, make 3 different ones and use them when you want to play them. If you ever sell the board, you can always offer the adapter for an additional price in case someone wants to play it in a JAMMA cab, too...
 
I bought 2 earlier this year, but haven't gotten around to using them yet. I had him put an 18/36 on one and a 22/44 on the other, as that's what most of my oddball boards have. I got them mostly for testing stuff. I wish it had some slots in the center so you could route wires thru the center. It's also going to be a bit confusing the way the board is labeled. I shoulda had him put the smaller connectors on one end instead of having them centered. I'll probably just hand write a small label with the correct pinout and stick it to the board when I use it.
 
Yeah, they might be. I just figured I'd have something to play around with without having to order a bunch of fingerboards if I wanted to test some boards. Once I cut all the little jumper wires, it should go pretty quickly to wire one up or change it to another pinout.
