...and other remarks along those lines.

Actually, if you did that, wouldn't the protection circuits in the 
regulators just "fold back" to a tiny trickle current, or shut down 

Although, I dunno, maybe as the voltage fell, the circuits in the 
semi-precious Commodore chips would have a brief chance to go into some 
horrible linear conduction mode and hurt themselves?
