Here's the latest: 2 new prototypes are undergoing final testing. The first is a single processor UMA1.7 system. The chipset is dubbed "Pangea2" and includes a USB, Firewire, Audio, Ethernet, IDE, PCI-X, AGP, and memory controller all on one die. The Pangea2 chip also sits very close to the processor module. The motherboard is 33% smaller than those found currently in G4s. It has 3 DIMM slots that take PC133 RAM and a 266MHz-frontside bus. Both IDE ports are now ATA/100. The processor included is a 933MHz PPC7450, and the system is equipped with a GeForce2MX card. The Airport controller remains on an add-on card, but the position has changed. The second system is identical to the first, except it supports DDR SDRAM. The graphics card is a GeForce3, and it comes with two 800MHz PPC7450s. Both systems use a standard ATX power supply, and are running MacOS X 10.0.2.
