Which version did you run, do you recall that?

I'm a bit surprised, to be honest, that VMS wouldn't be able to handle
that.  Is it as simple that Alpha, being 64-bit, would ordinarily
require more RAM?  Or were you performing complex calculations, heavily
using DECwindows and therein based programs, perhaps?

I'm asking because most VAXen with even less memory will run just fine,
I've noticed (like some of the IPv7.net nodes).

There's a mere 32 MB in mine.  I don't think I really want to use the
system for anything else than a glorified DECterm (especially since my
LK463 works fine on it) to connect to my I64 cluster.  32 MB should be
fine for that, correct?

Purely out of curiosity, since you brought this up: Are 100BASE-TX
ethernet adapters, since there's one PCI slot, available/known to work
in it?
