I installed this today and here is my early review.

Do the games swap at the push of the remote switch?
Yes they do. The prollem isn't the game swap, it is the signal strength and monitor clarity. When either of these boards is installed directly into the main Jamma harness in this cab, they both have great pictures and vibrant, clear video feeds. When they are installed in the switcher, the picture looks completely washed out on both boards, and is also weak and blurry. There is no blue present and everything looks very washed and yellowed. There is also no wiring present for test/service switch, as my recently working test and service switches now do nothing when pressed or flipped.

The good-
-You get 2 games in one cab within 3 seconds of pushing a button.
The bad-
-looks like you have to do a lot of hacking and extra detail wiring for volume, service/test and prolly many other features.
-Your video quality suffers horribly on both games.

I believe I am returning this unit.
 
Good to know. I have been shopping for one of these and was considering this one. Is there any particular ones out there anyone recommends?
 
I read this post a couple of days ago and was wondering if it applied to all the 2 in 1 jamma adapters. Looks like he did a bit of work but he got what he wanted.
he also had video and sound issues.
Just wondering what you think of it??

Thanks for being the gunina pig phet

I was considering one of these myself, guess that idea will go on the back burner until someone has one thats worth getting.
 
I've got the Mikes switcher, just trying to finish up the cab that its going into. Here's hoping that Mark finds the time to put his switcher into production!
 
I'll probably be sending the boards out to the fab this week... but I'll need to order 56-pin connectors from china =-P
 
I think its generally a grounding issue (with your buttons). Mine didnt have the start button grounded. I ran a ground up to it and it worked 100%. It seems to be a guessing game, they randomly leave of grounds! I did notice some drop off in video brightness with the switcher but not a loss in quality...
 
just wanted to show the video degradation on the GT2K board for you:

Plugged directly to Jamma harness:

Plugged into the switcher, with no video adjusting, just a straight swap:

Strangely, the GT2K board put out nearly perfect video when plugged into the jammaboard 2 in 1 switcher by itself, when the WCB wasn't plugged into the other edge connector.
Video splitting between 2 power hungry IT boards = the suck
 
Thats what my Lethal Enforcers looked like with LE2 on the second jamma connector before I added the relays. If they had designed this right they would have added the relays themselves, sure it would have only cost them a few bucks more a board.
 
Well Tim got back with me and doesn't seem real concerned about the issues this thing does or doesn't have, but he is using what I paid for this as a partial credit towards a 6 in 1 when he gets the return. I hope the engineering is a little better.
