Ok, silly me. I thought a 160K disk would be FM, not MFM.

Doesn't work. I have an unregistered version of 1.44. I have a
registered version of 1.2x (something like that) but I can't find it.
I tried all kinds of different formats for the hell of it and none work.

How? DOS doesn't allow you to do this. Don't have a Linux box handy.
Don't have time. For fuck's sake, didn't anyone ever write any decent DOS
utilities to do this shit? (Yes, I know I am whiny, but I'm tired.)

Of course: DOS 6.22. The last true DOS. The only OS MS ever did that was
actual pretty stable and robust.

1.44 unregistered.
The problem still remains I don't know if my controller handles FM. I
don't even know if this is my problem, or if I even need my controller to
handle FM. The disks I'm trying to read purport to be double density
anyway. What the hell am I rambling about? I have no idea. I'm lame.
I'm going home.
