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. >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").

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.

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. Guy
