Ah, the mighty 11/60; boy, but that takes me back. We bought one to
replace our ageing /40, and I was fascinated by its octal display (yes, I
wrote an idle loop to shift its digits back and forth; there should be an
article somewhere in the AUUG archives).
Story time: DEC were flogging the /60s real cheap here in Oz, because a
deal with a major publisher (Murdoch? Packer? Who knows?) fell through
at the last moment, and they had an entire warehouse to shift.
Trivia: the thing was micro-codeable, and I had dreams of implementing the
Unix call/return sequences as single instructions, but I never did get a
round tuit.
