I don't understand.  I think that you may have been confused by previous
postings.  There are currently two types of SIMMs that are usable in the
Mac: 256K SIMMs and 1MB SIMMs.  The '256Kx4' means that you are using four
of the 256K chips.  With the SE/30, you must put the SIMMs into the machine
in sets of four.  That means if you buy a 1MB SE/30, you can install four
of the 256k SIMMs (256kx4) to bring your machine to two meg.  But to go any
farther than that, you will have to remove some (4) of those and install
some (4) 1MB chips to bring your system to 5MB.

A/UX is like any UNIX system: it needs lots of disk space for utilities.
I suppose you could get by with running A/UX on a system with a 40MB
hard drive, but you would probably have to strip it down (maybe get rid
of manual pages, utilities that are not used, etc.).  

But one question: if you are considering a SE/30, are you sure that you are
wanting to consider A/UX?  You do know that A/UX on an SE/30 is not supported
by Apple (maybe in the future, but not now), don't you?

Maybe I made a mistake in my previous postings in referring to memory
using the '256Kx4' notation.  Maybe it should have been '4x256K'?  I don't
know...

I know the Macintosh creates some confusing situations, especially with
memory upgrades, so I completely understand why some people are concerned
with what they can and can't do.  I hope with the help of the people on the
net, we can prevent problems like those that occurred here at Ball State
last year:  2MB memory expansion kits were purchased, one for every Mac II
that was purchased earlier.  No one knew that you need 4M to upgrade, so
it ended up that every other person received their upgrade...  Case learned:
if you are not absolutely sure, make sure you ask someone.
