Playchoice 10 DM to a Jamma 6 in 1 Switcher! Dreaming, I am!

I was having one of those moments were I was thinking about, danm it would be nice to get all the PC-10 games in one cabinet. I had originally thought about going the Red Tent way with PC-10 conversions. However that still required changing out the populated pcbs. Even though its easy to switch pcb's out of a red tent. So the next thought was, can I build a PC-10 DM 6in1 switcher.

The practically of it, was for me, wasn't there. Its usally easier sometimes to take existing hardware and mod it. So this led me to think, is it possible to pin out the connections from the PC-10 DM's (two connections, consisting of 20pins & 56pin edge connector) to a Jamma Finger board.

My first concern, due to my more recent issues with my PC-10, was voltage. Which I wont lie, is still looking like its going to stop this idea. Unless I can figure out how to get and use right, a step-ups and step-down regulators into the harness. Or better yet, find a way to upgrade the switcher to use the 24v, vs the 12v. If thats even possible. Just brain storming here.

On the up side of things, The're less then 56 pinouts between the possible 76 pins on the two connectors avaliable from the PC-10 DM PCB. Actually, leaving 10 unused of a possible 54 to 56 potential pins, including the key. Thats only possible due to potentially soldering multipile GND's to the same pin. Same goes for the +5V.

I've actually spent a few hours putt'en around and did up a jpeg of my idea. If the voltage issue can be resolved. This could turn into something for someone possitive. Potentially allowing you to put all the PC-10 games in one cabinet. No more switching boards in and out.

You will notice that the counter hasn't been listed on the centre pinout. This is due to it being connected to the +24V. Which is still an issue with this idea.

I'm not sure I totally understand what you're trying to show in the pic, but I'm pretty sure you're not going to be able to do that unless you also plan on adding circuitry.

The JAMMA switchers that I know of only switch some of the signals... the others are simply connected and isolated with diodes, or left unconnected. In other words, you can't do things like switching the second monitor signals or extra buttons using unused JAMMA pins (unless you add your own switching circuits).

+24V is just used for coin counters, right? Do you really care about switching those? Most likely, you can replace +12V with +24V though, assuming the relay can handle +24V.

Yeah, I get that impression that the +24v is only used for the Counter from the schematics. Also, yes its not that important. Atleast to me, it isn't.

I havn't seen a 6 in 1 switcher in person. So I have no Idea if each version out there doesn't use the un-used pins. If what you say is correct, that they isolate each un-used pin, then I'll just have to figure something out. But again this is just brainstorming right now.

The purpose of the picture is a few things. One it shows the pin out from a Playchoice 10 dual monitor (edge connector, and pin connector). As well as a stand alone Jamma pinout. The centre one is a jamma, with were I would put the PC-10 pin outs.

This would be achived by using a jamma fingerboard. Sorta like making a harness adapter to connect the PC-10 board to the 6in1 switcher. The connectors would plug into the PC-10 PCB as normal, but then I'd wire those to the Finger board. Giving me the ablity to mount the PCB's anywhere in the cabinet.

I'd then have to reverse the process to connect the Switcher back to the PC-10 wire harness.
