Without thinking much about it, I'd say that mounting any
real blinkenlight console on a 11/44 is *not* trivial!
Of course, grabbing UNIBUS address- and data-lines and wiring
that to the lights is trivial, but to get all panel functions
(LOAD ADDR, DEP, EXAM, etc). working on an 11/44 is more work.
I guess there are more people on the list who have a boring
PDP-11/44 with a dull panel, that would like to make the /44
more sexy with an 'appropriate' panel. The "upgrade" is,
of course, done in such a way that it can be undone ...
I (we) do not have a /74 panel :-( , but I'd like to hear
what approach you are thinking of, Don.
Hmm, you could do it like I did as add-on to SIMH. Hardware
with some intelligence reads the front panel and translates the
switches to messages in ODT syntax which are send to the 11/44
monitor program ...

Subject: Re: Original 11/74 front panel
Actually I was thinking of making a replacement/alternate
front panel for my 11/44 using the 11/74 panel.
Add real blinking lights/switches connected up to the real
UNIBUS/memorybus.
The 11/44 panel is *way* too spartan looking, and the 11/74
panel would fit just perfectly on the front of the box.
