This was under SunOS 3.4 and the MIT X server, without much besides
the X server and an xterm or three running.  There were many other
(faster) machines on the net for things like xfig, idraw, window
managers, etc.  Response time was limited mostly by processor speed,
not swap speed.  

OpenWindows and 4.1.1 are gluttonous on memory.  The X11/NeWS server
tends to take at least twice as much memory as a straight X server.
(Yes, it does more, but those extras are NOT X.)  I can see them
grinding a 4 meg machine into the ground - especially with swap over
the net.

You need a dedicated machine for that, of course.  Something like a
six processor Sequent.  :-)

I suppose I shouldn't open my mouth until I see it and play with it,
BUT, I think a 4meg 3000UX with local swap should be usable with X.
With only one user.  With most of the common daemons disabled.
Without "too many" X clients.

Ok, maybe 8 meg would be a lot better...  :-)
