[NTLK] 7448 G4?

[Tony Morrow]

Most likely. The 1.42GHz upgrades were 7445 G4 processors. They were slower
than the 7447 versions in clock speed but had a huge L3 cache that made up
for it. For most tasks a 1.42 GHz 7445 was just as fast as a 1.8GHz 7447.
The only thing to worry about is if the upgrade you are looking at is for a
Mirror Drive Door PowerMac. Those systems were different from the
Sawtooth-Quicksilver systems.
