Can I use the replacement power brick for my Dual USB "Snow" iBook G3 (700MHz I think, from GainSaver) for the PowerBook, or must I buy a replacement 1400c(s) power supply from eBay?

Also, I may have a Clamshell iBook G3 (Blueberry) power cord somewhere from an old Clamshell I had a few years ago. Would that work?
