Obviously some hard decisions would need to be made about which questions to actually ask, but a voting system, while crude, might allow the question database to self-prioritize before the event.

I have to admit that the question I immediately wanted to ask this group is very offtopic, but I wanted to add the above suggestion anyway because I know others likely would come up with good questions. FWIW, here's what I thought of:
The source code to SketchPad turned up online several months ago: http://www.computerhistory.org/collections/catalog/102726903
I'd love to see a functional TX-2 emulator that can run SketchPad, and I'd be very willing to commit time to making it a reality. But the source scan is of extremely poor quality, AFAIK comprehensive in-depth info about the TX-2 isn't really out there, and no hardware survives.
A better scan would be an excellent start. I'm in Australia, or I'd have volunteered the time to rescan everything a very long time ago.
From there, much more info about the TX-2 is needed.
I'm reminded of http://martin.poupe.org/casio/ (select "assembler information", the site uses frames) who reverse-engineered and wrote an assembler for his calculator without knowing anything about the architecture - but he had hardware he could experiment with.
Again, I realize this is incredibly offtopic...
