Issue with sync using the Yanton Gallag jamma adpater off of Ebay
This is the adapter I was using when troubleshooting my PCB. My monitor would just display scrambled garbage So I new it was a sync problem. I found this post on usenet by Pinballer. “The one for Galag to jamma sold by Yaton. If you are he has it wired wrong and you won’t get it to sync. The little 5 pin plug on the video board is RGB sync GND and his adapter is wired RGB GND sync. You need to switch the white and black wires in the connector”.
Gallag CPU side daughter card missing or not seated properly
Gallag all zeros on startup
I’m not sure what causes this yet, but its not the power supply.
