Hmm... that size sounds different than the one I have - my memory is
a card that is square and about 8" on a side.

I can't say for sure, but largish (capacity) 5.25" drives _should_ auto-park
(parking was an issue for transporting < 100MB MFM drives, but later units
usually got over it), and the beauty of MSCP is that you can just throw a
drive on a controller and there's no host-side configuration.

Oh, yea.  We had an RA60 at work, c. 1987.  It was handy to be able to
change packs to change the OS, but in practice, we virtually never did
so.  I received a short rack with a couple of RA60s in 2000, and haven't
had occasion to power them on yet (I'd rather focus my energy on putting
my RA70s to use - similar capacity, *much* less power).
 
For that matter, I wouldn't mind finding an RA72 or two... size without
the wallet-sucking motors.
