The not-so-secret code name for the logic board used in Apple Computer's first G4 PowerMac computers. Also written "Yikes!".

The "Yikes" G4 PowerMac was shipped in the slowest 350 and (later) 400 MHz configurations only; the faster 400/450 and 450/500 MHz G4's available at the time used the newer "Sawtooth" board. It was basically a G3 "Yosemite" board modified slightly for the new processor. The "Yikes" G4 PowerMac lacked several desirable features added to "Sawtooth", including internal AirPort capability, an internal FireWire port, and no AGP slot. The resultant cost was about $400 less, however.
