I needed to setup this kind of configuration a few days ago. I have an 80Meg
internal hard drive (the 3 1/2" Quantum), which through entirely my own 
fault crashed.  I was able to recover all 78Meg I had on it using the
Symantec Utilities.  However, my only options for doing the backup was to
archive onto approxiamtely 140 floppies or on a single volume that could
hold the entire contents. The only large hard drive I had access to was an
80Meg 5 1/4" Apple internal.  All that needs to be done to accomplish the
hookup is an IDC daisy chain cable and a Y power cable.  The IDC daisy chain 
cable is simply like the ribbon cable that currently connect the drive to the
motherboard, with the addition of another connector in the middle. The cable 
can easily be made with parts from any electronics store, with the most 
complicated thing being making sure that all the pin 1s match up (ie not very
tough...).  The Y power cable can be purchased from nearly any computer store
as it is the same cable needed to hookup 2 internal floppies in IBM PCs and 
ATs.  The SCSI protocol and hard disk drivers support the configuration without
any problem or modification.

The 3 1/2" Quantum 80Meg is an amazing drive.  It is blazingly fast and very
quiet.  I have never had any problems with it in extensive and abusive use.
The drive has an on board 64K RAM cache that speeds its already quick 19ms
access time to roughly 12-13ms.  I cannot recommend it highly enough.  If 
you are interested in purchasing one, I have a source that sells them for
$1075.  If you have any questions, call me or e-mail to:
