Hi all,

I just purchased a TEAC FD-55GFR 1.2MB 5.25" floppy drive for my
MM/1.  I cannot seem to read CoCo OS-9 formatted disks with the
following dmode parameters:

name=c1
 drv=1 stp=3 typ=$24 dns=$01 cyl=40 sid=2 vfy=1 (off) sct=18 t0s=18
 sas=8 ilv=3 tfm=0 toffs=0 soffs=1 ssize=256 cntl=$0000 trys=0 lun=0
 wpc=0 rwr=0 park=0 lsnoffs=0 totcyls=80 ctrlrid=0 rates=$10
 scsiopt=$0000 maxcount=65535

When I attempt to read, I get an error #247.  The light comes on and
the drive is apparently trying to read the disk.

I recall hearing discussion that some 5.25" drives use a different
spin rate to read hi-density while others use a different data rate.
While I'm not trying to read a hi-density disk in this case, I wonder
if this drive will work as a 1.2 meg floppy?

Does anyone have any experience with this drive on the MM/1?  I would
appreciate any answers.  If I can't use the drive, I'm taking it back.
