What are you looking for that you can't do with a PC that autoruns a specific game in MAME ?

Just sticking once custom PCB in a JAMMA cabinet and having it work like that, without a separate computer or encoder, perhaps?

AndyWarne:


Motherboards with JAMMA on-board are readily available in the coin-op trade. We have thought about reselling them a few times.

But we have not owing to various reasons: They are really expensive, and they are always a few years behind current PC technology and are low-powered units. Using a J-PAC and a standard micro-ATX board is much cheaper and more versatile.

matsadona:

I have two of these boards, that have a compact flash drive. It is based on a DOS frontend that can be tweaked to add other ROMs.
The hardware is really old and weak, but upgrading the CPU and RAM makes it a little better, but in reality it only runs the classics without flaws.
The concept is really great though, with a standard PC motherboard in the bottom, and then a Jamma I/O board on top.

Here's a free product idea for you -- a mounting frame that has the J-PAC and mounts a Micro-ATX board. The USB headers are all standard on them, so in theory you'd be able to just screw the MicroATX board onto it, plug a jumper between the JPAC and the mobo's USB2 header, patch the VGA across and give it power. For bonus points, add an interface to the J-PAC that can be wired into the ATX power button connectors, too, so you can power on/shut-down with a shifted button combo or something.

You'd be looking at maybe $120 or something, all up. That's less than a lot of the xxx-in-1 JAMMA boards, and if the Pi is too slow someday, you can replace it with a $100 PC.

Less than that.
depending on what game & how many inputs it needs.
you can wire the controls directly to the GPIO pins & you can fit a console only OS that autoboots one game on a 1gb sd card.

If you use an old crt TV pi has the RCA out.
If you use an LCD panel you can use an HDMI to DVI adaptor.
