Pretty hard, without at least a very modern re-design of the power converter,
as I suggested originally.  Two hours of battery life would be at least 2.5 AH
at 12 volts, and that is not a small package.  Battery technology does not,
unfortunately, advance at the pace of Moore's Law.

Not at all.  Any 12 volt external supply will do nicely, as long as it can
supply
>1.2 A for the required duration.  A supply about 6" x 4" x 4" should do for
a couple of hours, even if lead-acid.

Yes, it would--but an old Toshiba laptop running an emulator would make
and even better one, particularly in the display quality.  Despite their high
"collector" value, the //c LCD display was a terrible display--no backlighting
and terrible contrast.
