Device initialisation
#6
I'm not using a flippy mod, just a plain ol' unmodified 3.5" floppy drive (SONY MPF920).  I tried setting pin 33 low on startup, but it didn't make any difference.

I've just tried an ALPS DF354N062F, and that's not showing any signs of the same problem.  However, I do know another user using an Amstrad 3" floppy drive with an external PSU, and he's reporting the same symptoms.  His drive has an adapter to convert the wiring, but it's a simple mapping and shouldn't involve any flippy changes.

I don't have time to run any more tests at the moment, but later I'll try to confirm the head movement by seeking in ~20 steps and stepping out until I see the TRACK0 line signalled.
