Short post today….
So it turns out that some of these BurgerTime don’t use composite sync and will have issues connecting to a JAMMA setup.
I’ve been sitting on this information for a few months already, got distracted and forgot to post it. It came back to me when I found this version of the board for sale recently. So… here it is, the information on this specific issue and a mod to address it can be found at the following page:
Data East 20 Pin Video Connector
Hopefully this will be useful to someone out there.
