I had discovered that information this morning too. I suspected as much
because the drive only went to the middle of the opening on the diskette.
The cool thing is I have the Teac documentation for this drive. I found it
in one of the Gimix binders I have. There is actually a jumper to set the
drive to 48tpi mode. I doubt I will care about that ability in my
situation. At least not until I get another FDD working on the CoCo. I
don't plan on canibalizing the Gimix machines, this was a spare drive in
with my stuff.
