Oh, I'll definitely need to use the 25-pin. I'll post a drawing of the max board outline for that size.

Components for the video mux arrived today. The DB-25 backshell has four small plastic bosses inside each half to locate the included cable clamp; these are easily removed with a small flush cutter or X-Acto blade.

I made a CAD template for the PCB to fit this backshell and the DB-25 connector, then printed it at 100% and cut it out to verify fitment. Pads for the connector's solder cups align well and the PCB fills the shell nicely. Drawing is attached.

My PCB layout for the mux will need a little finessing to fit this board outline, which I'll do in the next couple of days. I expect to have boards ordered by Fri, then I'll assemble one and send it to Alec for firmware testing.

Project update: A prototype PCB for the video multiplexer is assembled and ready for programming. I'll mail it to Alec next week so he can test his firmware.
