(This is exactly the same from the 28th Anniversary Contest)
Based on 3d models by zone66x and tmzwx, I have made shell printouts for a cable that is built from an ethernet cable that uses solid copper wiring.
This design handles both SH2 CPUs. If you want to use the MIDI as well, you need a different connector. Personally, I have used a separate RJ12 connector (Phone line) for that.
I also plan on updating the design to allow for dupont pins as well, unfortunately one of the issues I have encountered is the thinkness makes it hard to use dupont pins with casings around it, but I will get it figured out.

Below here are the pin outs used for various connections.
Using CAT5E cabling.
