xplicitly prevent you from installing it either; so if you install the
latest-and-greatest HP-UX on
that obsolete HW, it's unsupported, but at least it'll work.
In many cases it is because of the additional engineering work that
would need to be done to get it to work:
- any interface changes in the lower level kernel will
need to be done on all the copies of the vm system; that's
work times 3 if we supported sun4c, sun4m, sun4d
- older CPUs lack the necessary instructions for certain
atomic operations. That requires us to have multiple
library copies because we need to make use of those instructions
- for S10, we don't want to support a 32 bit kernel forever;
again a great engineering $$ savings
- dtrace has no chance of working on sun4m or earlier
