Title: Video Sync question
Post by: anunaki on May 01, 2013, 07:47:01 PM

Hi,

I have a Universal Mr Do PCB I want to make a Jamma adapter for. So I looked up the pinouts and I found out the Mr Do uses both horizontal and vertical sync on pin 5 and 6. Jamma only uses one sync on pin P.

How can I fix this?

Download the Mr. Do! manual and do the combined sync mod if it's not been done already. The combined sync is put on an unused pin.

There seems to be a composite sync signal on pin c. I'm, going to practice on my soldering to make an adapter.
