OK, thanks.
TBC, I'm looking at this from the "DEC replaced Ultrix with OSF/1"
angle, not really paying attention to VAX vs Alpha.
I'm more interested in getting rid of old operating systems
than old architectures, in the sense that those could potentially
hold back newer tool/compiler requirements. Modern tools running on
VAX is fine with me.
Thanks,
