Users looking to improve the performance of their 12-inch PowerBook G4s may want to turn to a
new MAChSpeed CPU upgrade
from Daystar. The new upgrade replaces the existing CPU with a 1.67GHz model and doubles the size of the internal cache. The upgrade costs $449.
Daystar Technology upgrades your PowerBook itself using trained technicians. The company offers three-way shipping choices. Free US ground delivery is now included; if that’s not fast enough, Daystar also offerings 2-day, overnight and “Weekender” service for an additional fee.
