As promised: the design of the CMPTR signal breakout board is released! Does it work? Yep. Is it cheap? Not really. However, it a nice option to have if you have a Sony PVM with a CMPTR connector and you want to use RGBS or RGBI/CGA/TTL.

A couple of extra photos of the CMPTR board and how it hooks up to the PVM. It's still crazy that Sony decided to use a DB25 cable for RGB/RGBI/CGA/audio...not sure if it wouldn't have been easier to just break those out on the back. Either way, it's not something I have to worry about again.
I'll end up posting the schematic and PCB stuff once I verify that the 2.1 version of the board doesn't have the same issues that this one does. They're minor, but I want to make sure it's 100% good to go before posting them online.

Done with this project, everything except for the audio port worked (not a huge issue, but annoying). Passed in CGA via the DB-9 connector, RGB via the BNC connectors and the Sony PVM was more than happy to display the signal.

Okay, got the new version finished. The BNC connectors are for RGB + Sync, and the other two BNC connectors were removed and replaced with a DB9 connector for the glory that is CGA. Kept the RCA audio port on the side of the board because audio will mostly go in directly to the PVM. Overall I'm much more satisfied with this layout and connector choice than the previous version.

After doing some digging on the CMPTR 25-pin interface, I think I'm gonna change the design of the CMPTR adapter. The IBM Luma pin and HSync pins kinda scream CGA (e.g. IBM 5151) so I'm gonna rip out two of the BNC connectors and run RGB + CSync on one side via 2x2 connectors. Beside those will be a DB9 connector running RGB, IBM Luma, H/VSync which makes a lot more sense.

Welp, went ahead and broke out every signal that goes over the CMPTR connector. All of the signals go to BNC connectors except for the audio which gets a special RCA connector. There is a bank of DIP switches that pull selector signals to ground as well. Still need to get all of the signals routed, but that should be pretty straightforward.
