My MM1 drive is set to 33 spt starting with sector 0. So that's 0 - 32.

I got caught using an 'odd' setup. However, it was as large as I could get
onto a floppy.
80 trk, 2 sid, 10 spt, and 1024 bytes/sector. That gives ~1.6MB. Oh, the
'got caught' was because I didn't record just what format I'd used, and
couldn't remember it at all. The Anadisk programme reminded me what it was.

BTW, I don't suppose you hve the OddJob (oj) programme on your MM1? I've
lost mine, along with a bunch of other files off my original disks.
