Ya, I’m confused, built it on a breadboard and worked fine with DIP but designed the PCBs with SMD as I wanted it to be an add on for the Atlas. Was gonna make it open hardware too for those that DIY.Will let you know in a couple of weeks how it goes with Frank's through-hole PCB design. Although, SMD shouldn't matter. What does your PCB design look like @XianXi? Would you mind posting it?
Correct, switch is to bypass the circuit as I’m assuming it might be like how some PCBs might not like it while others do.Looks solid (nice hand soldering too). What is the switch designed to do? Split CSync to separate H and V Sync? Or bypasses the sync pulse regeneration entirely?
In any case, will let you know in a few weeks how it goes with Frank's design with my F3. Might get a JAMMA adapter for my Phoenix board too. Got the parts from Digikey today. Just waiting for Osh Park to send me the PCB's now.
