Logic Board Connectors

The figure on the following page shows a Power Macintosh 8100 80 logic board. Caution It is important to note that the Power Macintosh 8100 100 and 8100 110 Series logic boards have a thermoelectrical cooling device that attaches directly to the microprocessor's heatsink. You can identify this cooling device by the black and red wires that run to the right of the heatsink and plug into the logic board via a keyed connector. This device is not a serviceable item. Do not unplug this device or you...

Key Points

Three key points to remember about a PowerPC processor-based Macintosh system It's a Macintosh it's compatible it offers tremendous performance. Apple's PowerPC computers feature the same user interface as their 680x0-based predecessors. Users can mix RISC-based and 680x0-based Macintosh systems on the same network and exchange files and disks between them. In addition, users can run both 680x0 and native PowerPC applications on the same Power Macintosh system simultaneously. Compatibility is...

Apple RAID Software

Apple RAID Redundant Array of Independent Disks software protects data from loss during a disk failure and enhances the speed of data storage and retrieval. It is available for all Power Macintosh Workgroup servers. Data protection is achieved through disk mirroring, a data storage scheme in which identical data is stored on two different disks. Apple RAID can also be configured for disk striping, a data storage scheme in which successive units of data are transferred to several disks at one...
