Jed:
You will need more than just 5V for your mobile computer. The good news is
that you can actually BUY a dc power supply for your box. I would assume you
are looking for something basic pentiumish. Do a search for DC computer
power supplies and find the retailers site for more info. I had the link
book marked at one time, but I just looked and it's gone.
Next, you can snag very inexpensive laptops that can be ideal for mobile use.
Good pentium quality laptops can be found with warrenty for less than $300
from IBM. Surely there are even better deals than that if you look around.
Nice thing about a laptop is that it includes a screen, and can typically be
easily adapted for 12v vehicle operations.
Sounds exciting though!
Have fun. 73 and tatah
