Hi!
Last year at CommVEx, Jim Drew once spoke of a John who restores 5.25" floppy drives.

"John buys drives off the internet, cleans them, aligns them on an oscilloscope, test them, etc"
I restore vintage AT&T UNIX PCs, and other equipment manufactured by Convergent Technologies.
These machines take the older 360k disks (only), and support 8 or 10 sectors per track formatting only on double-density disks. (High-Density disks will not work).
The UNIX PC uses these models:
TEAC FD-55B-01-U
or the
TEAC FD-55BV-06-U
I could not get the FD-55GFR model to work, so I am guessing that only the older versions of this drive, as I list above, will work with the UNIX PC.
Does John have any restored versions of this, or can he do a restoration on one of these that I could ship to him?
Thanks everyone, much appreciated!
