I have been thinking about the praticality of using a computer in a camper
where the only power source is 12Vdc.  Battery powered laptops which might run
off the camper's power are available, but you pay twice as much to get half
the functionality with a laptop.  Since the internal AT power supply takes
120Vac to produce +5Vdc @20A, -5Vdc @.5A, +12Vdc @8A, and -12Vdc @.5A,
shouldn't it be relatively easy to cook up a modification to the power 
supply (or a replacement for it) which would run directly from 12Vdc power?
