I had the same issue with one of those drives. I think I may have it but I
need to source a belt to fix it. The black goop that used to be the belt
got all over the mechanism. It was a pain to clean off completely.

I haven't seen any mention of greaseweazel types of "flux" readers. They
read the flux changes off of the floppy and then interpret them with a
separate program.
I use this to analyze DEC RX01 & RX02 8" floppies.
I know it works with FM, MFM and GCR disks as well as single and double

Yep. But they offer to do the legwork for you so there’s that.

All I could see was a paragraph stating that anything not picked up at
