s time....typically, much sooner. Many more details will be made available to our Reader Sponsors (thanks to information embargoes which prevent Web publication but not semi-private reporting...at least for the immediate future; we hope to post these reports on the Web site before too long) in Special Edition #9, which should go out within 24 hours.... But for the convenience of our readers, here are some of the predicted details of the new PBG4: *PPC 7410 G4 processors at 450 and 550MHz....unless Apple can pave the way for use of the higher-speed 7440 processor, which with no external L3 cache support can reach 600-700MHz+ while offering power usage just within the realm of possibility for portable applications. *ATi RADEON Mobility 7500 graphics accelerator with 16MB of DDR graphics memory *Slot-loading CD-RW/DVD-ROM combo drive on high-end model; possibly CD-RW only on low-end model *Backlit keyboard technology has been tested with PBG4s and iBooks, but we have no reliable information that confirms it will be used in this revision. *More bundled RAM. As part of a general move at Apple to reduce its memory costs and increase amounts of bundled RAM, the new PBG4 is expected to have 256MB of memory in the low-end model and 384MB in the high-end version. Expect to see similar increases in the PowerMac's bundled memory in the not-so-distant future. The uncertainties of these times extend deep into the heart of the future of the Mac platform....but expect Apple to begin some very strong moves toward a successful future indeed with a short-notice Apple Event sometime later this month or in early November. A portables revision is all but certain for that timeframe.
