I just made a working cable for DVI for Model 200 that doesn't need any twists in the cable and is polarity keyed and shrouded.
It's annoying that you have to solder two parts together, but the end result is a cable that is keyed and shrouded, AND fits in a 200 (also 102 but 200 is the difficult one) On the 200 end of the cable you just solder together a through-hole pcb solder type shrouded male pin header and a "wire to board" 40 pin idc connector. It's a bit fiddly manually holding the two connectors just right until you get one pin soldered. Then still have to be careful not to melt the pins out of the connector. But in the end it's probably actually easier or more reproduceable than splitting and twisting all those pairs of wires and then trying to crimp them all at once. And a better/safer cable than using a double-ended male-male 40p header on an ide cable, because the male pins are shrouded, and both connectors are polarity keyed. https://photos.app.goo.gl/h53pg61U0qEAIawx1
