OK, so I just bought an Atari 520ST, and it didn't come with any documentation
other than a "getting started" book, so I know very little about it.  So
please bear with me if this seems like a simple question, or has been
covered before....

The 520ST has a hard disk port, but I can't find anywhere what kind of
hard disk it's supposed to attach to.  I know that one can, somehow,
attach a SCSI disk to the ST.  I have a Micropolis 85Mb ESDI drive that
I'd like to attach to my machine.  Using an Emulex MD21 adapter, I can
make this look like a SCSI drive.  What other pieces would I need to
attach this drive to my machine, and where can I get them?

While I'm at it, are there any good books describing the internals
of the ST?  I've been to just about every computer bookstore in the
city, and even a few outside the city, and none of them carry *anything*
about the ST.

Thanks,
--Pat.
