I'm affraid that there's no nice/modern solution as this was already at the time a dead standard !

1) Lot of 100TPI drives were made by (for) commodore - Mechanicals are generally still alive, so, no real problems on this point
2) Some manufacturers produced shugart 100TPI drives - that "should" be compatible with normal controlers
3) Some of those (shugart) drives had optionally 96TPI or 100TPI mechanics with identical electronics
4) Finding proper 4D floppy disks is nearly impossible those days (2D works time to time but HD can't)

Now, all depends on the goal what can be
1) Have a brand new 8050/SFD1001 compatible drive ==> I would say forget
2) Read (write) some 100TPI floppy disks in "modern" world
->2.1) Have a working 8050/8250(LP)/SFD1001 and a zoom floppy interface ==> The easiest path ? (*)
->2.2) Have a catweasel, a suitable PC, and a 100TPI mech/shugart interface ==> Should be possible (**)

(*) I actually have this type on configuration available
(**) Searching since years ... I've possibly sourced a pair of brand new Micropolis drives in the other side of the earth ... that might be on their way "home"

Could you run the stepper between steps the way CNC stepper controllers do?
