300 rpm only
I'm sitting here looking at a TEAC FD-55GFR
5.25" floppy drive with a
TEAC-branded SCSI daughterboard mounted on it. Picked this thing up for a
buck at a flea market and don't know much about it. Anyone else familiar
with it? I'm not even sure if this is a HD drive.
The _drive_ is HD, I am not sure what the controller can do, though. The
suffix letters of Teac drive numbers seem to indicate the specs as
follows :
A : 40 cylinder single-sided
B : 40 cyclinder double sided
C : 77 cylinder single sided (??? I have never seen this)
D : 77 cylinder double sided (??? or this)
E : 80 cylinder single sided
F : 80 cylinder double sided G : 80 cylinder double sided, 360RPM, high density
(1.2M for PCs)
Does both 300 and 360. (can replace the E and F with correct jumpers).
H : 80 cylinder double sided, 300RPM, high density
(1.44M for PCs)
Never seen an FD55H.
