RE: [techtoolslist] 9100 Floppy drives.

I found this site that may have the drive you need (Mitsumi)
http://www.computertradeexchange.com/inventory/MADGE.html

And this site has some information on jumpers for the TEAC
http://www.bassontop.com/drivetext.htm

I don't have a 9100a, so I may be out on a limb here but, the drives you
need are 720k drives. So, getting a 1.44mb drive to work in it I would
assume would require some rewrite of the 9100a floppy drive routines.
Seems like it may be more work than it's worth. But if you look, maybe
you can write some code for it.

Subject: [techtoolslist] 9100 Floppy drives.

I have a couple of dead floppies on my 9100's and was wondering if
anyone
knows how to set up a 1.44 to run on them. The Drive Select has to "0",

but then nothing much happens. The latest version of the System setup
disc
(Rv1.4 - for SCSI) seems to support the Canon HD drive but I have no
idea
what drive that was supposed to be.

The drives supported (Rv1.4) are:
Canon (MD350)
Sony F17
TEAC FD235
Mitsu(mi?) MF355C
Canon HD (unknown model)

The service manual says (Pg 3-34) that the floppy control lines are:
DS0, DS1 (Drive Selects - D0 for 9100)
Spare (not used - is this the High Density enable?)
MINI (selects floppy clock speed for 5-1/4 & 3-1/2 or 8")
DENS (single or double density - but how does this fit in with a Canon
HD
drive?)
P0, P1 (write pre-compensation time 0, 125ns, 250ns, or 375ns)
EN-ENT (Floppy Interrupt)

Anyone have info on any of these drives and can identify the parameters
needed?

Thanks!
