Sorry, I have no 720kb floppy drives. Wish I
did, a lot of people
are asking for them!
Many "1.2M" drives can be substituted. You need to strap it for
300RPM. Watch out for density select, and READY V DISK-CHANGE
Teac 55FG is a nice one for that.
Am I missing something ?
Or are we all?
1.2M is 5.25" and 720k is 3.5"
The original poster asked for 720K drives for a "GE Workmaster"??
Is THAT 5.25" "quad density" or 3.5"?
Either way (3.5" double density 720K or 5.25" quad density 720K) both
drives are virtually impossible to find today, and /if/ you can find one,
chances are it isn't in perfect working order either. Pretty much the only
real option now is to have someone refurbish/align the existing drive if
you can't adapt a PC-compatible drive.
Even 1.44MB 3.5" drives that could be adapted via jumpers to work in an
application that used a non-PC 720K 3.5" drives have become incredibly
scarce (out of the dozen+ that I had on my spares shelf, I only had /one/
drive that worked properly after cleaning and testing, the rest seem to
all need an alignment). The reason this has happened is because so many
people treated these drives as commodity parts (I'm looking at you, Amiga
community) and tossed out drives that only needed minor mechanical work
and/or a head alignment. This is especially true with 3.5" drives and I'm
currently working on setting up something where I can align 3.5" drives
because I can't find anyone else who still does it.
