HP 95LX computer, 1991
The HP 95LX, HP's first palmtop personal computer, was roughly the size of a large pocket calculator, but possessed as much computing power as a desktop personal computer system. It weighed only 11 ounces. The machine had a financial calculator, a telephone and address program, Lotus 1-2-3, a simple text editor and an infrared link for transferring data.
The 95LX is widely considered HP's first PDA (personal digital assistant). It was the first palmtop computer with built-in Lotus 1-2-3.
