I think there may be some future for this box, but quite
possibly not with
any flavour of unix. We've got an old dec3000 that ran DU
happily for years
until one day it started generating a mass of memory errors. The
only
way we got it to boot was to take all the memory out of the top
tree, which
left it with only 32Mb. Strangely it didn't seem any slower...
Anyway we
replaced it (it was our web server) with a linux box and, after
a while, put
VMS on it. Suprisingly it was totally happy and has now been up
for about
3 months. Similarly we've had nonames running DU which dumped
cores
repeatedly with memory related problems which disappeared under
NT. Mind
you removing all the cache memory (one of the workarounds we
found)
actually made a lot less difference to overall performance than
you'd expect
(mind you, from "slow" to "a bit slower than slow" isn't that
noticible providing
you don't try and benchmark it ;-)

p.s. bit of an unrelated topic but has anyone ever seen anything
coming from
the FreeVMS people (www.free-vms.org)? Their machines up but the
web
server seems to have disappeared a long while ago.
