Unfortunately, the 765 does a "reset" of the chip whenever it sees the
index. It can handle NOT having an index hole (AFTER formatting),
but excess holes will keep it from working.

Hi Fred
When I first got my first PC, I didn't have anything
but hard sectored disk that I'd used on my H89. I made
a foil disk that I put in with the disk to get around this
problem for formatting. It had a large hole that most
of the time only exposed one index hole. Placing it
in the drive was tricky but with access to the top of the
drive I made it work.
Of course, I later bought a box of 360K disk but this
trick did get me started.

I believe the ubiquituous NEC 765 (et al) does its
"index" on read by
scanning for the 0th sector ID (which is 1 :-) The index hole is only
needed for formatting, and that only for compatiblity.
