was wondering if anyone here has wired up a ipm invaders , M10 hardware ?

it has vertical sync and horizontal sync.

i tried putting them together but it wont work.

am i gona have to find a specially made RGB monitor with separate syncs to run this thing ?

or does anyone know a way around this ?

your help and time appreciated.
 
I found this discussion and links helpful when trying to get Q*Bert PCBs to sync in a JAMMA adapter. You might have to experiment (some people have had success just twisting the two syncs together or using just one of the syncs) or build an adapter. It seems that some monitors can handle a wider variety of syncs and others are too damn picky!

Not familiar with that Space Invaders hardware - the Midway and Taito boards I'm familiar with just output normal composite video (black and white).
