From the discussion
A few top-level comments from Lobsters, shortened. Read the full thread on Lobsters.
I quibble a bit with the bottom. VAX was intended more as a follow-on to the PDP-11 than the PDP-10. It was even _called_ VAX-11 initially. It certainly subsumed that class of _system_ but I don't think that was the original intent, and architecturally it was closer to the 11s.
Agreed, the PDP-11 was a minicomputer and the PDP-10 was a mainframe. The VAX was a minicomputer with clear PDP-11 heritage. Over time DEC did a good job covering low to high end with it and VAXclustering pushed it into unique space that covered the need of a separate mainframe ISA.
