Can you really imagine that HP would be able to sell new systems for new
projects, when the operating system runs on top of a processor emulation? I can't.
Charon Vax is a nice and good product if you have vax software and don't want to
or can't migrate to Alpha VMS or something entirely different. I can't imagine
companies to build new software products on the base of Charon Vax however.
