Subject: Versafloppy II Question

Can anyone out there help me with a question about a Versafloppy II FDC
made by S.D. Systems, Dallas, Tx.???  I'm running an old S-100 system
with this controller, and a generic CP/M (not S.D.'s version).  It was
OK running 8" SSSD, but got very slow when I switched over to 5 1/4".
I think that the problem is the sector slew.  No slew was slow, a slew
of 5 is worse!!  Does anybody know the magic number for this hardware??
I'm using a PD version of a DD cbios.  S.D. originally supplied Versa-
floppy II software (in ROM) that used a 128 b sector.  They later went
to 256 b sectors.  Did the slew used in the S.D. version of CP/M change
with the change in sector size??  ANY help/comments will be appreciated
