Boy, I'm so glad that is settled. Now I know how
to identify any 5.25"

Wow. Why didn't I ever think of that?
Until this moment, I've been using silly things like model numbers,
testing, and something no one has yet mentioned:
Don't you think that is a bit rudimentary?
The step rate marked on the stepper in degrees.
Sometime this
can yield a clue.
Unfortunately, that is hard to find these days. I cannot recall
seeing that on any half-high drive.

Subject: Re: 5.25" drive identification
The beige faceplate on 360K is yellower than on 1.2M
360K has jumpers for drive 0,1,2,3; 1.2M has jumpers for A,B
360K has a screen that is usually white on black; 1.2M has a screen that
is white on blue. (If it bluescreens, then the drive is a 1.2M)
