More than one Jamma Connector, swtiching quickly

[canardo]

does any one know way of connecting multiple devices to one jamma connector and having some sort of switching device between them

I was thinking of using several jamma connectors , plug the boards into the connectors and the wire to  a singe jamma finger board and then having a toggle switch across the power supply of the different boards, there by which ever one had power would come on?

Would this work are there any problems I havent thought of, or is there better solution

help appreciated

A search for MultiJamma will get you loads of results (perhaps more than you want).

Clay Cowgill put together a kit that consists of a controller board that connect to your JAMMA harness and up to 8 satellite boards that connect to your JAMMA boards. You wire a dedicated button to switch between games and may require additional power supplies to power all of the boards. I have one and love it. The downside is that these can be hard to find and Clay has a LONG turnaround time. I have an additional issue because two of the games (GT2K and SurfPlanet) I have in mine use standard controls to adjust volume, so switching between games can lead to ear-splitting volumes. Clay's kits do pop up here or on RGVAC from time to time (I bought mine here from Goz and have seen a couple since then).

There is also Mike's Double JAMMA Adapter, which I have never used, but is more readily available (I think).

A while back, BYOACer arcadefever picked up a 3-way JAMMA switcher board with a remote control:

BYOACer statjakt was thinking of building a JAMMA switcher based on one he had made for his PC-10/VS cabinet (and I wish I had one of those!):

That ought to get you started.

I have a JAMMA gun cabinet project (which I would like to make Multi-JAMMA-Gun) where none of these solutions really fits and I have thought about doing something similar to what stratjakt did, although a mechanical switch would also work for me (kinda like what you are suggesting, although I would include the guns along with the power).

Let us know what you end up doing.

cheers for the advice and will certainly contribute back and let you know how I do it

and yes my switch will hopefully be switching more than just the std jamma connectors as ideally would like to customise various kick harnesses into it, will let you know what I come up with!

This is going to be mainly emulation cabinet so I dont strictly need the cab to switch the power, I also am not worried about having to turn it off in order to switch games, ideally though I would like to leave my genuine boards in the cabinet as well (its a golden tee electrocoin cab so lots of room in there)

am more thinking xbox, ps2, dc and pc (for mame), So as long as the video would not bleed to the other components I may just end up wiring 3-4 jamma connectors to one jamma finger board, and do the old fashion way of swapping over the connector for this and the real pcbs
