JH>> The APC 420 Smart UPS Pro unit I have here just uses a 12V 7AH
 JH>> battery - - just 84 watt-hours of power.

 ml>> wow, that's a "little" one > all
mine are 650s and up with two
 ml>> 1000s and an 1100...
 ml>> FWIW: yes, the APC UPS' are what i'm wanting to either enhance,
 ml>> extend, or replace... but $$$ are a concern...

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

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

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

now, that's a thought...

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

i believe i have two or three of those around here... you wanna pay
shipping? you can have the monitors and the machines... i know that one of
them was in working order some years back >

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

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

so i remember >
