Any way to make a JAMMA switcher? To swap from JPAC / CPS2?

[Kajoq]

I'm wondering if there is any way to make a switcher of some sort, similar to a KVM switch for a PC.

I'm wanting to have my JPAC running to my computer for MAME and also have my CPS2 Super Street Fighter 2 X connected with the ability to flip a switch or something and change between them.

I'm thinking theres got to be a way to wire this, but my wiring skills are rather mediocre.

Has anyone ever attempted something like this?

Yeah, I've scoped out those multijamma boards before but couldn't make out from their pictures if that would work right . 
After inspecting it a little closer and scanning that thread it looks like it should connect up just fine with their connectors.
It sounds like I would have to kill the power supply every time I wanted to swap to the JPAC.  Now, to see if I can figure out a way to replicate that for less than 180 haha
