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. -- jkenner @ mindspring . com__ I Support Linux: _> _ _ |_ _ _ _| Working Together To <__(_||_)| )| `(_|(_)(_| To Build A Better Future. |
