another stab.
Did you clean the heads AND the leader strip? I had one with so much fuzz on it that it
would have surely gunked up the heads straight away. You can clean the leader with
alcohol, just like the heads. Sometimes these things need multiple cleanings...
I assume you've got this connected to a PDP-11 or Vax that you're using to write
to it, and that this isn't the SCSI flavored TK50Z. I ran into a similar problem with
a TK50Z on a linux box - constant shoeshining. Turns out that I had to set the buffer in
mt. After that, it worked just fine.

I cleaned pretty much everything /but/ the
leader. It's worth a try,
but it looks pretty spotless.

Yep, it's the
"regular" TK50 hooked up to a Qbus TQK50 controller.

Speaking of the SCSI-variant, I have a TK50Z-FA for my pile of
MV2000s. I had been thinking of trying to upgrade it to a TK50Z-GA
(new ROM and optionally a SCSI ID switch), but I'm curious if it'll
still work with the MV2000. If it won't, it shouldn't be hard to rig
up a double-sized ROM and a high-bit switch.
Does anyone know if a TK50Z-GA works on a MV2000?
