At least around here, the very FIRST drives that RS
made available for
the
Coco were Shugart SA400s. That is a 35 track drive
with the spiral
groove
disk. Allison pointed out that there was a later model
(SA400L) that
could handle 40 track. BTW, if you have decent machine shop
capabilities,
the SA400 could easily be modified for more tracks, but
it is NOT a
handheld Dremel task.
Actually if you have SA400s better to replace them with most anything
else unless it's strict preservation. I still have a few for that
reason.
Those things were horrid.
Later drives around here included Tandon (TM100-1)? and
TEC. Tandon
uses
The TM100 was far better.
Was the "TEC" label on the drive itself, or
on the case (possibly a
drive
had been changed?)
Likely TEC on the outer case, thats why I said open it and see if they
are SA400s.
