Ah.  you hit on the problem.  Anyone who runs UNIX on a 386 or A3000 WITHOUT
a windowing system is crazy.  

Here are a few RAM sizes to take into consideration:
	My ESIX (System V 3.2.2) kernal is 770K
	It takes 2 meg just to boot, after all the dameons,mail and other
		network drivers are loaded.
	Bring up X Windows with MOTIF, open Xclock, Xbiff, and three Xterms
		and your total RAM useage is just under 8 meg. (one user!)
	The average X-program is one meg of executable.
	GCC's executeable is about 1.8 meg.
	GNU Chess is about 1.5 meg.
	When compiling, GCC takes up a meg of RAM just for DATA.

Now, sure, UNIX has virtual memory-- but it is not the Holy Grail.  It provides
a nice 'catch' for when you do run out of RAM.  It also provides a way of
telling you when it has done so-- it starts swapping to disk every time you
switch windows!

If I had about 4 average users, and no X-Windows, then 4 meg of RAM would
probably work fine.  But I have 2 heavy duty users, X-windows, and Netnews.
 
Also.  How can you not run X-Windows on an Amiga/UNIX?  It's not like your
console's native mode isn't ggraphical windows or something... :)'
