The HP 95LX (F1000A, F1010A), also known as project Jaguar, was the first MS-DOS pocket computer or personal digital assistant, introduced by Hewlett-Packard in April 1991 in collaboration with Lotus Development Corporation.

The HP 95LX had an NEC V20 CPU (an Intel 8088 clone running at 5.37 MHz) with an Intel Corporation System on a chip (SoC) device. It cannot be considered completely PC-compatible because of its quarter-CGA (MDA) resolution LCD screen[7]. It ran Microsoft's MS-DOS version 3.22 and had Lotus 1-2-3 built in. Other software in read-only memory (ROM) included a calculator, an appointment calendar, a telecommunications program, and a simple text editor. It also included a CR 2032 lithium coin cell for memory backup when the two AA main batteries run out. For mass storage, the HP 95LX had a single PCMCIA slot which could hold a static RAM card (which had its own CR 2025 back-up coin cell). An RS-232-compatible serial port was provided, as well as an infrared port for printing on compatible models of Hewlett Packard printers.[8] In character mode, the display showed 16 lines of 40 characters and had no back light.

Successor models to the HP 95LX include the HP 100LX, HP Palmtop FX, HP 200LX, HP 1000CX, and HP OmniGo 700LX.
