VAX Hardware Docs

Hi,

I was wanting to try out OpenBSD on various hardware architectures.
I could do it only x86 and amd64 till I read miod's blog

http://undeadly.org/cgi?action=article&sid=20060825232507

where I came to know of SIMH :-)

So I did install OpenBSD on VAX too

I would like to know if there are books available for VAX architecture like the

Peter Norton's book.

or any other plave I can lear more about the VAX architecture?

Thankyou so much :-) especially to miod :-)

Kind regards

Siju
