I have a 15-year-old Gateway Handbook 486 that only takes 5~6v at well under 1A (with a hard drive, much less with a CF card). It can run forever on 4 AA NiMH batteries, or from a USB port! http://en.wikipedia.org/wiki/Gateway_Handbook http://en.wikipedia.org/wiki/Gateway_Handbook Unfortunately, the screen is total crap -- I don't mind that it's grayscale, but that it's an ancient bottom-barrel passive screen.
