I hope it's o.k. for me to ammend your list:

PDP-11:  The addressing modes of this mini even influenced a major
	 language (C).  Now that's influence!!!  Notable ripoffs are
	 the 68000, and the Vax-11 (the 32032 is a Vax-11 ripoff).

Multics: The segmented architecture was imitated (unfortunately) by
	 the Intel 8086 - 8088 and esp 80286 (remember all those
	 articles in Electronics on "rings of protection" in the '286 ?)

CDC 6X00:Where did the idea for a scoreboard come from ? From
	 Seymour's machine!

CRAY-1:	 Introduced vector processing, and the idea of having huge
	 numbers of registers in a machine (later copied by RISCs).
	 Pioneered the concept of a horribly complicated machine
	 to program.  Put compiler writers/researchers back into business.

Intel 432: The ultimate CISC == Horrible failure.
VAX-11:	 2nd-place for CISC == Success.  9-11 cycles/instruction
	 These machines had a major influence on RISC designers
	 (e.g. disgust).  Also, inept Berkeley computer designers
	 (small designs only!) and small dies in hands-on VLSI courses
	 had a big impact on RISC computers (just kidding).
