<Most soft-sectored controllers (the LSI ones used in most other micros)
<didn't use the index hole for very much, except during formatting. A
<suprising number of machines will work quite happily with the index

Try it you will find many cases where that is not totally true.

<Hard sectored controllers (like the one in my Z-90) do need the sector
<holes to find the start of a sector.

Reason for that is by counting holes you don't have to look for marks on
the disk.
