This is true.. I verified this fact once back around 1990, on a Tandy
1000 I had dug out of the trash at high school. I had one cable for
the floppy, and it didnt have a twist. When I added a second floppy
(that sat on top of it), I just spliced a plug into the cable, but had
to change the jumper position.
