"Sources said more than a dozen software engineers are tasked to Marklar, and the company's mainstream Mac OS X team is regularly asked to modify code to address bugs that crop up when compiling the OS for x86. Build numbers keep pace with those of their pre-release PowerPC counterparts; for example, Apple is internally running a complete, x86-compatible version of Jaguar, a k a Mac OS X 10.2, which shipped last week. "
"The likeliest solution to the Motorola impasse, sources said: A desktop version of the 64-bit Power4 server chip in the works from IBM, which co-developed the PowerPC platform alongside Motorola and Apple and has provided CPUs for a variety of Macs. Sources told eWEEK that Apple and IBM are collaborating closely to equip the Power4 with the Altivec vector-processing capabilities built into the PowerPC G4. IBM is expected to discuss its new CPU at October's Microprocessor Forum. "
