Thanks to all those who responded to my request.  Emboldened by knowledgeable
netters, I went ahead and installed the Quantum 80.  Here's a summary of the
process for those interested:

The physical mounting required a little modification of the bracket that came
with the Quantum.  It was designed to fit in the spot for the stock internal
hard disk, but only required a little cutting to fit in the second floppy's
place (the two tabs that anchor it are the same size for both brackets).
I did have to remove the internal floppy to mount the Quantum, and then put
the floppy back due to clearance problems getting at the screws on the
Quantum's bracket.

Power was no problem at all; a standard 4-conductor cable fit the motherboard
and drive connectors with no modification.  The SCSI bus wasn't too difficult
either, needing only about 2' of 50-conductor ribbon and 3 connectors.

I found the terminating resistors on both drives and removed the CMS's
because it was in the middle of the cable, and I set the Quantum SCSI ID to
0.  I'm beginning to wonder if I should have done that, because now the
machine doesn't always mount both drives on a reboot--I suspect the Quantum
comes up to speed much faster than the CMS and the CMS gets ignored.

In all, I'm very pleased with my current setup--I have Virtual installed,
and the difference in paging with the new drive is appreciable.  Not to
mention how *quiet* the Quantum is.

Thanks again to all those who responded.

( :^) isn't it nice when something works out right for a change? (^:  )
