It was my impression that the relevant SAU's for '020/'030/'040 machines
_were_ being built with the appropriate -cpu settings.  I believe Domain
was built -cpu 3000 for my DN4000 here.  Perhaps I'm mistaken.  Or do I
misunderstand you?

No, we didn't want to outright orphan all the older nodes.  There aren't
many around, but enough to deserve some minimum level of support.  If we
built the compilers -cpu mathlib_sr10, the older nodes couldn't run them
at all.  It's one thing to sacrifice convenience of the few for sake of
performance of the many; it's another to obsolete the few entirely.  We
aren't quite there yet for the compilers.  (Ignoring for a moment the
question of whether a DN320 would be able to do any meaningful work with
recent compilers, given their present 'heft'...)
