There my well come a day when a 32bit system with a 64 or at most 128M
address space and the performance characteristics of a sun4c is no
longer a viable platform for NetBSD. I do not see that happening in
the near future, but its possible that in 20 years, or 40, or some
even longer time it is no longer feasible to support such ancient
hardware and still deliver what is expected for a modern OS.

Coming from someone who is using NetBSD/vax and playing with
NetBSD/dreamcast I can safely say I have hardware much closer on that
curve than sun4c :)

Still, I suspect NetBSD/sun4c support may outlast most of us on this list :)
