Poqet PC (1989)

The Poqet PC is a very small, portable IBM PC compatible computer, introduced in 1989 by Poqet Computer Corporation. It was the first subnotebook form factor IBM-PC compatible computer that ran MS-DOS. The Poqet PC is powered by two AA-size batteries. Through the use of aggressive power management, which includes stopping the CPU between keystrokes, the batteries are able to power the computer for anywhere between a couple of weeks and a couple of months, depending on usage.

Grid Compass (1982)

The Grid Compass (written GRiD by its manufacturer GRiD Systems Corporation) was one of the first laptop computers when the initial model was introduced in April 1982 (the model 1101[a]). The computer was designed by British industrial designer Bill Moggridge in 1979, and first sold three years later.

The design used a clamshell 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.
