Can it run on B:? I have SF314 that is noticeably slower then usual
builtin (in STE/STF) floppies. I could test it with that.

I made 2 versions of the program, you can try fdc_idxa.prg or fdc_idxb.prg and try the same floppy in the 2 drives. What ST model do you use ?

    I'm improving the timings for the floppy controler and I'd like to
    have some results for the attached program on real hardware (STF or
    STE, not TT or Falcon).

    This program measures the time between index pulse on a floppy
    (which depends on the RPM settings for the drive) ; on my STF, I get
    the following values :

    Index Pulse OFF / ON duration after restore track 0 :
    000099e8 000002e8
    000099e9 000002e8
    000099ea 000002e9
    000099ea 000002e8
    000099ec 000002e8

    Values will change a little, but should stay in this range.

    Could someone with a working STF/STE test this program and post the
    results ? I need results from different machine to measure the
    relation between RPM and index duration.

    Just copy this fdc_idx.prg on a floppy and run it ; it will read
    track 0 and do some measures during 1 or 2 sec (nothing is written
    on disk)
