I needed more space between the halves and saw a youtube video where someone has opened one up a there are 15 through wires plus a ground. Digging though my box-o-cables I remembered that I had a bunch of old HD15 VGA cables that would make great extensions so I spliced HD15 ends and tried it out.
Turns out that VGA cables are not 15 lines through, but bond several pins together. Damnit. A true HD15 serial cable is now en route and I’ll get to test out my extension…hopefully by this coming weekend.
As soon as the new cable arrives I’ll post a full write up. The funniest part (to me) is that I almost used a USB C breakout connector but decided against it because I was worried about finding a good/affordable USB-C cable with 1:1 wiring. Got bit in the ass anyway by not hitting my vga cables with a meter, lol.
