Let's clear the air here....

The Video Chip and the SID chip in the 64 use the 9vac.  So does the
cassette.  If you are crafty, you could re-do the power supply inside 
the 64 since 12 volts is greater than or equal to what you need
inside.  To get a modem to work will also require a hack to the modem
to get -5v, but I don't suppose you are going to be needing a modem
in your car.

Check over your schematic for a 64 and I think you will see what I
mean.  An out of date, but good enough schematic is in the back
of the 64 programmer's reference guide.  What ever you decide will
require a good 5V @ 2A, and 9VAC @ 1A (or whatever you come up with).
