Blackbird was Apple’s code name for a new line of PowerBooks based on the 68LC040 processor. (The LC version of the 68040 draws less power but has no FPU.) These PowerBooks introduced a full-sized keyboard with 12 function keys, replaced the trackball with a trackpad, had a 640 x 480 screen, and even had built-in stereo speakers. They were also designed so they could later be upgraded with a PowerPC processor.

These were a big hit since they were the first notebook computers from any manufacturer with any of these features: a trackpad, built-in ethernet, 16-bit stereo sound, built-in stereo speakers, an internal expansion bay, and auto-sleep when the lid was closed.

In the field, users raved about the dual battery slots, providing up to 4 hours from a charged pair of batteries.

Cautions

• Batteries are prohibitively expensive, usually well over US$100 each – and the computer uses two. Condition your batteries regularly; don’t let them run down and die.
• The 100-series and 500-series PowerBooks do not provide SCSI termination power, depending on external SCSI devices to provide it. For more details, see SCSI Termination Power.
