    I've got a friend who wants to put a computer into his Van.  Now, he
wants to run the system off the battery without going through an invertor,
since the invertor generates a lot of heat and very heavy current draw.

    The system needs +5V @ 5amps, +12V @ 1amp, and -12V @ 100mAs.  The +5
and +12 are no problem, it's the -12.  Like, it's just not available
on a normal 12v car batttery system.  So, any ideas?  I have no desire
or time to sit down and design an +12V dc to -12V dc convertor.  Is there
a commercial power supply available that can be feed +13.8 volts, (car
battery), with outputs close to those listed?

     Any ideas?
