Yes, the Morrow DJ/DMA Floppy Disk Controller will drive 5" as well as 8"
disks.  I quote from their Tech Manual (Rev 1, Apr 82, Morrow Designs,
all rights reserved), "The Disk Jockey/Direct Memory Access (DJDMA) Floppy
Disk Controller is a single board S-100 subsystem.  It communicates with both
8 inch and 5 1/4 inch floppy disk drives.  Up to eight drives may be
connected to the controller - with the limitation that no more than four of
each type can be accomodated.

"Special programmable bipolar LSI logic makes it possible to read and write
media with almost any format, be it hard or soft sectored.  Presently the
controller supports soft-sectored IBM compatible 8 inch media and hard-
sectored North Star compatible 5 1/4 inch media.  In the spring of 1982,
IBM and Radio Shack 5 1/4 inch soft-sectored media will also be supported.
Existing controllers in the field can be upgraded by replacing two of the
ICs on the unit. ...

And in the source code for my CBIOS (provided by Morrow for my own 8"/
5Meg HD system), I see drivers for Fujitsu M2301B, M2302B, Shugart SA4000,
and Memorex winchesters, Seagate ST-506, ST-412 and CMI CM-5619 8" drives,
and the North Star CP/M 1.4 and 2.X SSSD 35 tracks, SSDD 35 track, DSDD
35 track, plus same for 2 and 4 k groups.  My vendor down in Alabama talks
about interfacing Tandon DSDD 5 1/4 drives with no real problem.

So, I guess so.

Hope this helped.
