Morrow Pivot

Specifications

The original model, retrospectively called the Pivot I, was unveiled at COMDEX/Spring '84 in May 1984 and released in November that year.

The Pivot I had an original list price of US$2,995. In February 1985, Morrow revised the LCD to have an electroluminescent backlighting panel, allowing users to operate the computer in the dark. With this adjustment, the Morrow Pivot became the first battery-powered portable computer with a backlit display.

The Pivot II, introduced in May 1985, improved the LCD to support native CGA resolutions—that is, 320 by 200 pixels in graphics mode and 80 columns by 25 lines in text mode. The Pivot II was optioned with either one or two 5.25-inch floppy drives. In March 1986, Morrow introduced the Pivot XT, including an internal 3.5-inch, 10-MB hard disk drive in addition to two 5.25-inch floppy drives.

Clones

The Pivot II design was licensed to Zenith Data Systems in February 1985 for $1.5 million and sold as the Zenith Z-171. Zenith sold over US$27 million worth of ZFL-171s to the United States government, mainly to the Internal Revenue Service—notably beating out IBM and their PC Convertible clamshell laptop. In 1985 the general manager of Morrow Designs, Robert Dilworth, left his position to become CEO of Zenith Data Systems, a position he held for several years as part of Zenith's paying him to talk George Morrow into licensing the Pivot to them.

Osborne Computer Corporation licensed the original Pivot (not backlit, 80x16 line/480x128 display, 128 KB RAM, 16 KB ROM) from 1984 as the basis for their Osborne 3, known as the Osborne Encore in Europe.
