History

Development began in 1979, and the main buyer was the U.S. government. NASA used it on the Space Shuttle during the early 1980s, as it was powerful, lightweight, and compact. The military Special Forces also purchased the machine, as it could be used by paratroopers in combat.[5]

patent rights
as its innovations became commonplace.

Competitors

The portable Osborne 1 computer sold at around the same time as the GRiD, was more affordable and more popular, and ran the popular CP/M operating system. But, unlike the Compass, the Osborne was not a laptop and lacked the Compass's refinement and small size.

Models

The Compass ran its own operating system, GRiD-OS. Its specialized software and high price (US$8,000$10,000) meant that it was limited to specialized applications.

Compass

The initial model, the 1101, was introduced in April 1982;[3] The 1100 model designation were never released commercially, but featured in some pre-release marketing material.[6][7] The computer was designed by British industrial designer Bill Moggridge.

Design

The design used a

hard drives and floppy drives could be connected via the IEEE-488
I/O (also known as GPIB or General Purpose Interface Bus). This port made it possible to connect multiple devices to the addressable device bus. It weighed 5 kg (11 lb). The power input is ~110/220 V AC, 47–66 Hz, 75 W.
