Apple drops Yikes mobo for Sawtooth

And upgrades graphics to Rage 128 Pro

Apple has finally dropped its Yikes-based Power Mac G4 and filled out its line of professional-oriented desktops with models based on the more advanced Sawtooth mobo. Yikes was a version of the blue'n'white Power Mac G3's motherboard, knocked up by Apple engineers to allow the Mac maker to ship a bottom end G4 using components originally selected for the G3 line, such as PCI graphics cards. The more sophisticated Sawtooth mobo brought AGP support to the Mac, doubled the memory bandwidth to 800MB/s and allowed up to 1.5GB of RAM to be installed. It also supports Apple's AirPort wireless networking add-in card. In the shift to a Sawtooth-only G4 line, Apple has also upgraded the machines' graphics card to an AGP Rage 128 Pro and replaced the low-end box's CD-ROM drive with a DVD unit. Apple's online store continues to list the three basic models as 350, 400 and 450MHz, the speeds Apple shifted down to when emerged that the PowerPC 7400 (aka G4) would not run at 500MHz or more. However, according to reader reports on MacInTouch some US resellers have begun selling G4s at their original speeds of 400, 450 and 500MHz. Motorola originally said last month that it would have a fix for the 500MHz bug late 1999/early 2000. ®
