Because it's so long since I used any 360K floppies, that I could not
recall if some didn't have any hole. (But I did remember about the soft/hard

The 82901 specs I have don't mention if it's soft or hard sectored, but a few
diskettes I received with the drive (which are definitely for it) are single hole.
And the index hole.
What about it? There were some machines that didn't use the index
(such as Apple and
Commodore), but they didn't care if there was one.
Yes, I knew about Apple disks. http://everist.org/NobLog/20190106_hacked_appleII.htm
There were some that used 10 or 16 index holes
("hard sectored"). In
the unlikely event if these happen to be hard sectored, then others will
gladly take them off your hands..
:) Except I'm in Australia, so they could probably find them cheaper at home.
bgmicro sold at a very reasonable price. For me, most of the cost will be postage.
I send everything via shipito.com in CA (a reshipper) for consistency, tracking, and
significantly lower international rates due to their bulk deals with carriers.
Btw, I didn't deplete bgmicro's stock. They seem to mention on some items when
they
have limited stock, and they don't on the floppies. So likely have a LOT of them.

"360K" - 300 Oersted. vs 1.2M 600 Oersted.
Can you believe that is the first time I have ever heard the actual figures for the
coatings?
I knew the 1.2M type had a higher coercivity, thus the incompatibility. Ditto with
3.5" 720K
vs 1.44M.
Thanks for the detailed review, and thanks to the others adding more. Saved.
