ReadHat distributions seem to have a problem doing real small installations but
would fit without too much problem, Slackware would easily fit inside 80MB A, D
and N disk sets. But if size and obtaining HDD's are a problem you could
(performance may/would stink!!) run a ROOT NFS system off the larger HDD server
to NFS mount the remote systems as 'diskless' and use the local 80MB HDD for
DOS ethernet card support drivers etc (v small partition) and the rest as a
local swap partition.

RAM is so cheap these days, old 486's probably 4x4MB 30 -pin simms shouldn't
cost more than £10 each new. 72pin, put 1 16MB in again less than £15.

I think this is a learning exercise - isn't it so performance may not be a
major issue anyway ?
