Well, I knew I still had it (somewhere!) so it was not like I found it
at someone's garage sale (I worked on the development of the 11/74 CIS
back in the late 70s while at DEC). But it was just temporarily 'misplaced'.
As to how many of these exist, I would hazard to guess very few. The
11/74 was cancelled just after the design was completed ( a great
product management strategy :-) ) but a number of proto/preproduction
systems had been shipped to internal DEC sites (Maynard Mill and
Spitbrook Road IIRC). There were probably no more that a dozen or so of
these front panels produced (I'm guessing here) as the plan was also to
move to the 'electronic console' for remote diagnostic capability and
get rid of the manual lights and switches (an EMI nightmare!) in favor
of a serial console interface.
So how many of these panels exist is hard to say. I know only of one.

What do you think, Don, how many exist of this panel?
