Hi Eric
what would work best for me is a prototype board mounted with a PIC ready for ICSP,
but without the video chip, so that I can solder some test parts onto it.
I dont have any video sources or screens so when Ive verified the PIC works I
can send it back to you to check out the video.

Beautiful. It looks like our mux design with a single positive supply should work
fine. I'll get the ball rolling on a prototype, which I'll send to Alec to
stuff with a programmed PIC.
Alec: Should I add a couple of PIC12F683s to my parts order, or do you already
have them on hand?
Eric

Sounds good; that's what I'll do.
I'm going to order parts first, as I want to measure the inside of the D-Sub backshell
before I order PCBs. After looking at the 3D models of the backshell
and PCB together, I don't think it's going to fit. It looks like the pin headers
will be too tall and the PIC won't be able to be socketed. I'd like to use
a right-angle DB-25 connector to lower the board and gain more vertical space,
but there are only a few available with flanges to fit a backshell, and those
start at $10.60 ea., versus $0.64 for the solder cup versions. Stay tuned...
Eric

why would you want to socket the PIC?
