You could probably run any earlier SunOS. I used to run 3.5 on my 2/120
and 2/50, but I had 4MB in each, later 7MB in the 2/120. I also remember
getting X11R4 to build and run on the 2/120 under 3.5, but can't remember
how much memory I had at the time, just that it took 18 hours to build.

I'm thinking 3.5 would be lighter than 4.0.x. I remember thinking
about getting 4.0.x for my 2/120 so it would support SCSI disks
(besides ST506 and ESDI disks attached via Adaptec ACB4000 and Emulex
MD21) and deciding against it.

Last time I looked through /etc/rc* on a SunOS 4.1.4 system, I noticed
that nd support was still there, and thought that it was probably
still possible to get it to act as a boot server, even for SunOS 3 for
the Sun-2. I'm not real sure how you would install it with just the
tapes and a tape drive on the newer system though, but then I can't
remember how I got the 2/120 to boot the 2/50 either.
