Though Ritchie has portrayed the similarities as coincidence,

The influence of the 11's indexing [Bell] versus the 8 on C/Unix abounds, whatever your perspective on 'Macro' move instructions, they were certainly the obvious follow on rage, witness the Movc3/Movc5 in the Vax.

I've always enjoyed the notes K&R made following a non-disclosure presentation of the Vax, the most prescient I recall being a comment on the 512 page size.

I revered the 11, had Qbus machines which could be assembled with superior 3rd party components in places, scattered through my apt/basement as a student from the 23 through the j11 all the way up to a MV2.

Everything since has been anticlimactic :)
