A thought. Find a cheap *true* UPS. One that includes filtering. 

Then just run that off an inverter hooked up to some honking big batteries.

You can get away with a cheap and dirty inverter if the UPS has good
enough filters.

I wish I'd grabbed some old Compaq TTL mono displays years back when I
had a chance. You see, they got power (5 & 12 volts?) from a 3-pin DIN
connector on the back of the old Compaq Deskpro 286 systems. 

Rigging power for one of *those* would be easy. And 12V computer PSes
aren't *that* hard to track down.

Of course, even with one of those monitors, you'd be limited to Herc &
mono EGA modes (yes, there's an EGA mode designed for Herc type monitors).
