Market value of VAX 4000-96 - Re: Can anyone explain this to me ?

   That's
very insightful. The x86 has a fantastic security record. I'd
 certainly pick it immediately over some unproven, obscure technology
 like VAX.  I had no idea that the VAX instruction set was inherently more secure
 than x86. 
Well, the sarcasm you appear to be missing (whether deliberately or not
I can't tell) aside, I think it actually may be.

"There are two ways to make something secure: you can make it so simple
there are obviously no deficiencies, or you can make it so complex
there are no obvious deficiencies."  While I would hesitate to call the
VAX instruction set simple, at least compared to something like the
PDP-8 or even more modern RISC machines like MIPS or PPC, it is far
more orthogonal and cleanly designed than the horror that is x86, and
correspondingly easier to implement correctly.
