Apple PowerBook G3The PowerBook G3/400 (Bronze Keyboard/Lombard) -- formally a member of the "PowerBook G3 Bronze Keyboard" series as dubbed by Apple, but often referred to by its codename of "Lombard" -- features a 400 MHz PowerPC 750 (G3) processor with 1 MB of "backside" level 2 cache, 64 MB of RAM, a 6.0 GB hard drive, a tray-loading 2X DVD-ROM drive (onboard MPEG-2 decoding), and ATI Rage LT Pro graphics with 8 MB of SDRAM in a sleek black portable case with a 14.1" TFT active-matrix color display.

In addition to faster processors and the "bronze keyboard" for which it is named, the PowerBook G3 "Bronze Keyboard" systems are approximately 20% thinner than earlier PowerBook G3 models, have longer battery life, weigh substantially less and add dual display support. Also when compared to the "PDQ" models before them, the "Bronze Keyboard' PowerBook G3 models exchanged the ADB and Mac serial ports for dual onboard USB ports (while retaining the SCSI port), added 10/100Base-T Ethernet (up from 10Base-T) and dropped one of the two PC card slots.

Despite the age of this system, site sponsor Other World Computing has RAM, hard drives, SSDs, and other upgrades available for this specific Mac while supplies last.
