Misalignment of full-height floppy drive caused by a loose stepper motor coupling.

Hi, I wrote up this puzzling alignment experience, just in case it's helpful to anyone.

Aligning a full-height floppy disk drive when the alignment screw proves inadequate. Check the stepper motor coupling?

Well done guys!

THANKS TEZ!

I had done this on an Aerocomp Drive that was on my Model 1. I had a COLD Solder joint
inside the stepper motor that I re-soldered. That caused me to do the same type alignment.

I'm curious if you have tried the procedure on p95 and p96 of this document under Heading
"WILL NOT READ", where you fill a track with 0x2F and then adjust the read signal for max
signal? I've got 4 floppy's created with track 16 with 0x2F's DOS, NEWDOS, TRSDOS-3,
LDOS-5.

I'd think it would be a nice substitute to the missing Dysan Alignment floppy.
