Grid Compass
The Grid Compass is a family of laptop computers introduced in 1982 by the Grid Systems Corporation. The design for the Compass was rendered by Bill Moggridge. Owing to its clamshell design—the first in a portable computer—some historians credit the original Compass as the first ever laptop. This original model of Compass lacked an internal battery compartment, requiring AC power from the wall. Grid sold the succeeding model, the Compass II, in 1984 with an optional external battery unit. Grid replaced the Compass with the GridCase line in 1985.
