Which explains why nobody's ever seen one of these thingies...

You may have misunderstood. (Or perhaps I misunderstand how the PRAM battery is used.) I just was thinking that the primary drain on the PRAM/backup battery comes when the Mac is sleeping. If you could alleviate the worst of the drain, i.e., by providing an external battery for backup while sleeping, then the PRAM could last longer at it's other job, keeping PRAM safe while the machine is powered down. I was not thinking of keeping the 9V widget attached all the time. This part of the discussion, though, is apparently moot, given the first point above. - Eric. -- Eric Strobel (fyzycyst@NOSPAM^mailaps.org) ===================================================================== What if the 'Hokey-Pokey' really IS what it's all about?? ===================================================================== ---------- Duo/2400 List, The friendliest place on the Net!
