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.
