The following is cited from Wikipedia--------------------------------------------------------
DesignThe design used a clamshe...ll case (where the screen folds flat to the rest of the computer when closed), which was made from a magnesium alloy. The computer featured an Intel 8086 processor, a 320 × 240-pixel electroluminescent display, 340-kilobyte magnetic bubble memory, and a 1, 200 bit/s modem. Devices such as hard drives and floppy drives could be connected via the IEEE-488 I/O (also known as the GPIB or General Purpose Instrumentation 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.
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. 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.[3]
Along with the Gavilan SC and Sharp PC-5000 released the following year, the GRiD Compass established much of the basic design of subsequent laptop computers, although the laptop concept itself owed much to the Dynabook project developed at Xerox PARC from the late 1960s. The Compass company subsequently earned significant returns on its patent rights as its innovations became commonplace.
ProductionDevelopment began in 1979 and the initial model, the 1101, was introduced in April 1982;[4] the model 1100 did not exist, except in marketing materials.[5] The computer was designed by British industrial designer Bill Moggridge.
