The HP 95LX Palmtop PC (F1000A, F1010A), also known as project Jaguar,[8] is Hewlett Packard's first DOS-based pocket computer, or personal digital assistant, introduced in April 1991 in collaboration with Lotus Development Corporation. The abbreviation "LX" stood for "Lotus Expandable".[9] The computer can be seen as successor to a series of larger portable PCs like the HP 110 and HP 110 Plus.
HP 95LX has an Intel 8088-clone NEC V20 CPU running at 5.37 MHz with an Intel system on a chip (SoC) device. It cannot be considered completely PC-compatible because of its quarter-CGA (MDA)-resolution LCD screen.[10]
The device includes a CR2032 lithium coin cell for memory backup when the two AA main batteries run out. For mass storage, HP 95LX has a single PCMCIA slot which can hold a static RAM card with its own CR2025 back-up coin cell. An RS-232-compatible serial port is provided, as well as an infrared port for printing on compatible models of Hewlett Packard printers.[3]
In character mode, the display shows 16 lines of 40 characters, and has no backlight. While most IBM-compatible PCs work with a hardware code page 437, HP 95LX's text mode font is hard-wired to code page 850 instead.[3] Lotus 1-2-3 internally used the Lotus International Character Set (LICS), but characters are translated to code page 850 for display and printing purposes.[3]
The palmtop runs MS-DOS 3.22[3] and has a customized version of Lotus 1-2-3 Release 2.2 built in.[6]: 72 [11] Other software in read-only memory (ROM) includes a calculator, an appointment calendar, a telecommunications program, and a simple text editor.
Successor models to HP 95LX include HP 100LX, HP Palmtop FX, HP 200LX, HP 1000CX, and HP OmniGo 700LX.
