The 7.2 kg Macintosh Portable was Apple's first attempt at making a portable Mac. Released in 1989, it was received with very poor sales. This 16MHz Mac featured a B/W LCD screen, 1MB RAM expandable to 9 MB, a full-sized keyboard and a built-in trackball. The machine was powered by a battery that provided a up to 10 hours of battery life.
