I have a TRAK AT-D4 disk drive.  This is the double density,
double-sided drive that pretends it is two drives, using the
second side written backwards.  TRAK includes a slave port
on the back to control other drives.  I would like to know
what drives will it control, and what protocols are available
on the pins/edge-connector.

Part 2:  I also have an old(?) drive out of an APPLE LISA.
These are better known as APPLE's boondoggle.  This is APPLE's
own wierd design for double sided disks, with 4 R/W slots on
the disk (the two heads clamp onto the disk 180 degrees apart
from opposite sides, with each head having a felt pad opposite
it).  I think these would be fun to play with.  Has anybody done
anything with these before???


                   Thanks, I eagerly await any info....
