	Yes, in theory there are 2 ways you can...  

	1).  DC to AC converter will be the easiest, (and most expensive) way.

	2).  Theoretically, you could connect direct supplies, (+5 Vdc & 12 Vdc)
	     to the output of the regulators inside the 64.  The only problem 
	     with this option is you will not be able to use the CIA's internal
	     clock for timing, (it uses the 60 cycle from Edison to control the
	     timers), and the user port will also not get it's 12 Vac needed
	     for some interfaces.  (IE Promburners, some C-64 modems etc)...
	
	For me, option #1 would be the only real easy, (and 100% compatable)
	solution.

	I would have liked to, but I need a complete address to E-mail you.
	(Like !dude!bummer!you).  We don't support backbone addresses at this
