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.
Nice! Let us know how you get on. If you run into trouble, perhaps there's a DIN connector you could try?
RL is preventing me from playing, but it works 100% using a true HD15 (1:1 serial, not VGA) cable. Full build post TBD.
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.
