Another pretty good link for those looking for VMS history:

<http://gordonbell.azurewebsites.net/digital/Bell_Retrospective_PDP11_paper_
c1998.htm>

"A Retrospective on What We Have Learned From the PDP-11:
What Else Did We Need to Know That Could Have Been Useful in the Design of
the VAX-11 to Make Alpha Easier?

"VMS is the Architecture That Mattered. not PDP-11, VAX, or Alpha"
