VGA Monitor RGB input

Post by bioniclebert »

Ok, so the arcade machines monitor is broken, and I need to fix it. Upon studying the pinouts of JAMMA boards, I learned that the video used is RGB. According to this chart:
http://www.jammaboards.com/jcenter_jamma_pinout.html

However, the Sync line pin marked pin "P" is just called sync, and common monitors output h-sync and v-sync. I was wondering If I could hook up a monitor using a jamma board in this way, as in, how the sync lines would match up. Thanks.

EDIT: Well I've learned this is pretty much impossible, says a few sources. I guess either buy a new monitor or just build a MAME cabinet.

If you got an older pc monitor (amiga era) you could, but most new ones have a 30khz min. while jamma is 15khz IIRC

ok lets say I did. Where would I connect the sync line (from the JAMMA board) to? A combination of V and H sync?

You need a monitor that accepts Composite sync (C-sync). Most RGB Amiga and Commodore monitors work with this, and you can get them for cheap, if you can find them locally.

If you do decide to build a mame case, what will you do with the rest of the arcade machines' insides? I could use them. What type of arcade machine?

It is not junk! It is assorted goods with no current use.
