Here in the College of Architecture's Visualization Lab, we have

	- a sun4 server
	- ~15 sun3's
	- ~10 sparc's
	- 2 NeXT's
	- 8 SGI's of various flavors
	- 40-odd PC's
	- 30-odd Mac's

There are approximately 100 users with active accounts, but I would
say only about 20-30 are regular users.

Of the Mac's and PC's, only a handful have direct connections to the
server, so they are not directly our concern.  In addition, there
are various printers, scanners, and other peripherals that fall under
our jurisdiction.

The "we" above consists of a full-time system administrator, and a 
half-time assistant system-administrator (who is a grad student).
There is also a full-time staff member to handle most Mac and PC
problems, so there will naturally be some overlap.
