From the project
TTL-RS232 level-shifting cable for Tandy Portable Disk Drive
The BOM includes a grey cable. This black cable can be substituted if you want.
If you want to make 2 cables, one for Model 100 and one for PC/WP-2, then double the BOM components except for the cable, and cut the cable in half right in the middle. Otherwise just cut off the 9-pin plug to make one longer cable for Model 100 and other KC-85 clones.
Cut the unwanted plug off the cable. If building a Model 100 cable, cut off the 9-pin plug. If building a PC/WP-2 cable, cut off the 25-pin plug. If building both cables, cut the cable in half in the middle.
