A "syquest" is a hard drive with a removable platter larger than but resembling
the 3.5" floppies which are quite popular on many systems.

Believe it or not, I was running a Syquest as the primary HD on one 3B1
on which I was doing a lot of testing several years ago ... it was easier
just to pop in a new cartridge with a different kernel and/or other files
than it was to de-/re-cable different HDs.

I don't recommend anyone doing this (using a Syquest) unless you're fully
aware of the consequences: the kernel doesn't like to have the pager disk
removed while UNIX is running!  :-)
