Title: jamma boards and sound boards!
Post by: mrcram on June 21, 2005, 05:01:27 pm
I know jamma pcb boards have a seperate sound board, but some dont! I see all these boards on ebay but no sound board. I emailed this guy on one of them and he said that the sound was built into the board! how do I know which boards have sound built on them or not????

You just have to do some research on the board your looking for, it's real easy to find a picture of any PCB online to see if it has a seperate sound PCB.

I thought all JAMMA boards had built in audio amps

Nope ... even for single board games, you may require an external amp (I have an EggVenture like that).

Cheers.

And then sometimes you have a choice. My Galaga 88 board has two options. There is mono sound that goes out the via the JAMMA connector, and this is controlled through an onboard amp. And then if I want stereo sound instead, I need to connect seperately through some extra pins on the board. I don't know if these are amplified or not...

The vast majority of JAMMA boards have an onboard amp and DO NOT have a separate sound board.

Really, the only ones I have seen with separate sound board are stuff on Midway hardware. You could always tell that Williams/Midway and Gottlieb were REALLY pinball machine companies, by the way they did their hardware.
