It appears to be attempting to find track 0 by seeking repeatedly. But it’s stuck.

It appears that the DIR pin is operating backwards. When asserted, that should step in, towards track zero, and outwards when deasserted. So the T1200 is at track 0 and wants to step to track 1, but it's instead trying to go the other direction and staying at track 0. Repeat ad infinitum. I think I can pretty easily invert the GPIO signals.
