> Does anyone know if the ram from a 450Mhz G4 will work in a 733Mhz G4?
Mactracker <http://www.mactracker.ca> indicates that both models have
the same minimum RAM speed (8ns), so it should work. You might check to
see if the firmware version is the same on both G4s. See
<http://docs.info.apple.com/article.html?artnum=60839> for Apple's
article on firmware and RAM.

That depends in part on what system is installed on the older machine.
The Sawtooth shipped with 8.6; the Digital Audio with 9.1. The pre-X
installers tailored their installations to the hardware they were
running on; so it would be better to install a fresh system on the drive
after it's in the newer machine, especially if you're using a system
older than OS X.
If you do a clean install (recommended) rather than an update, you'll
either have to reinstall any non-Apple drivers or move them from the old
to the new system folder.
