: the TI-99 only uses it for the format routine, and there-

As I said, some use it, some don't. I got my FC5025 today,
and reading through the setup manual I discovered that the
drive recommended has a jumper that sets it to use or not
use the Index Pulse Hole. I'm going to just leave it open
and see if I can read a flippy disk. I'm thinking yes.
