Hmm. Ken Olsen once told me the same thing about the
PDP-5. Except for
the "micro" bit, of course.
This is also noted, though one must read between the lines, in the papers
on the 18- and 12-bit systems (specifically the PDP-4 and PDP-5) which were
collected in Bell, McNamara & Mudge, _Computer Engineering_. (I've had
occasion to re-read those several times the last couple of months, while
preparing material for our new site.)
