I modified the files /mac/bin/mac24 and /mac/bin/mac32 to add '$*' on the
'startmac' command.  That way, I can type 'mac32 -m5m' to start a 5M Mac 
environment, or just 'mac32' to use the default size (the size of physical
RAM).

So far as I've been told, 16M is the largest Mac environment that you can run,
but I'd expect that you could run that on a 4M machine with a 16M swap 
partition (so that you 20M virtual memory; 2-3M for the kernel, 16M for the
Mac OS, and some to spare).  It would probably swap enough to be very slow,
but it should work.
