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
