It appears (according to everymac.com) that the 7300's CPU _is_ on a
daughtercard.  If their database is wrong, I'm sure John can tell us.  ;)

If this is the case, do you have reason to believe that just plugging the
CPU card into the 7300 won't work?  IIRC, the daughtercard CPUs were mostly
interchangable.  I've used at least 4 or 5 different random hand-me-down CPU
cards in my 7500 and it never had a power problem that I could tell...
