The PowerBook G3/400 had a distinctive translucent bronze-colored keyboard and was often referred to by its codename, “Lombard.” The codename was a reference to its curvy case design reminiscent of the curvy Lombard Street in San Francisco.
The bronze-keyboard PowerBook featured a 400 MHz PowerPC 750 (G3) processor, 64 MB of RAM, and a 6.0 GB hard drive, and a tray-loading 2X DVD-ROM drive. The screen was a 14.1-inch TFT active-matrix color display.
The PowerBook G3 bronze keyboard systems were approximately 20% thinner than earlier PowerBook G3 models, had a longer battery life, weighed substantially less, and added dual-display support. This was also the first “professional” PowerBook to drop the ADB and Mac serial ports for dual USB ports. However, the laptop retained the old SCSI port.
