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
sectoring; 1 vs n holes.)
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.

Yes, I knew about Apple disks. http://everist.org/NobLog/20190106_hacked_appleII.htm

:) 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.

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
Thanks for the detailed review, and thanks to the others adding more. Saved.
