Sticking keys are normal if it's a datanetics keyboard (original). You can
recover the switches usually by flushing then with 91% ISP and lots of
mechanical motion. I usually pull the key cap off and use a needle nose
pliers about 50 times on each switch flushing it every so often using the I

I had a closer look at the Rev 2. The keyboard is non functional (all the keys
stick). The ROMs are applesoft, not integer basic (it has a ram add on card
too). It powers up but nothing happens. Would that still have us in the $2k
range?

Well I have had a look and there lots to see.

The lights are most likely not LEDs. Probably lamps.
Scaling it down is not possible.
The lamps and switches are already tiny.

Hmmm,
There is one example: PDP11GUI has a virtual 11/70 panel in it, which
can be used to operate all supported PDP-11's, including QBUS machines
and SimH.
As I programmed it I believed this was a "must-have", but honestly, it's
more kind of a "Pimp my Eleven" joke.
Personal credo now: bett

I'd quite like to see a fully fledged panel for Q-BUS based PDP-11s, or
even a VAX.

Yep. I have a spare blank datanetics PCB if you want to transfer your switches
