(Repeat of an earlier plea for help)
I constructed a simple motor latch to interface a Tandon TM-100-2A drive
to my A1000, largely for the purpose of getting files from my Amiga to 
a rather interesting graphics device at work through a rather un-
interesting 'blue' box. My problem is that since upgrading to a B2000
(4.2 rev) the drive no longer wants to work as a 'PC' drive, though its's
fine as a 40-track Amiga device. The symptoms are 'root directory full'
from PCcopy and 'error -4' from PCformat. Oddly enough the drive still
works fine in both modes on the old 1000. Can anyone shed any light on
what 'error -4' might mean, what differences might exist between the 
1000 and 2000 implementations of the external disk interface, and 
whether or not such a latch circuit needs any additonal 'tweeks' to 
operate on the 2000 ??
