The new bootblocks (almost commited) load at 7MB into RAM, as do Ultrix
bootblocks.  It's conceivable that everything prior to now _might_ run
in 4 or 6MB...

"zcat NetBSD-1.3.3/base.tgz" is approx. 37MB, the last snapshot was
45MB.  Add a couple of the kernel and then 10% and we're looking at
about 60MB with almost 0 space free.  Maybe 80MB might be a more
realisitic figure.  FWIW, I use a 100MB RZ23 for basic testing of
release stuff (including 32MB of swap).

I guess this should be cross-checked with
http://www.NetBSD.ORG/Ports/pmax/models.html.  Will you have a chance to
do this?  I do know for sure that the 5900/260 works - that's what 1.3.3
was built on!

And?  :-) :-)
