Have you considered making it a universal connector into the actual unit, and making different adaptor cables so the same unit can be interchanged between systems?
Yep, but by leaving the 23 pin D-Sub off, it leaves the holes available to solder wires too. There's detailed notes about how to use it on my website

You mean me make adapter cables for different systems, such as Atari computers? I could add an inline plug or socket onto the PCB design I suppose, for me to make adapters, or others. I'll probably try and sell all of this batch before I bring out another version, if at all. I'll wait and see how sales go first
