Brian SwetlandPCBs are back from JLCPCB and looking very nice. If I do another batch I think I'll reduce the width of the edge fingers area 1-2mm so it's just a bit less snug in the card slot. Time to do some soldering.
My soldering is not going to win any awards, but it should be good enough to get the job done. Time to see if I can make the firmware go.
I just realized I don't actually own any LCD displays with VGA in (though I do have a cheapo VGA->HDMI adapter around here somewhere). I do happen to own *one* remaining CRT, so I used that to try the test pattern mode. Looks like the VGA out side of the firmware is happy at least!
