200LX

The 200LX refers to a model of portable computer produced by Hewlett-Packard. Introduced in the early 1990s, it was part of HP's line of "personal organizers" or "handheld PCs" that aimed to bridge the gap between simple calculators and full-fledged laptop computers. The 200LX was notable for its relatively large screen for its time and its built-in productivity software.

Key features of the 200LX included a QWERTY keyboard, a monochrome liquid-crystal display, and a powerful Intel 80186 processor. It ran on MS-DOS, allowing users to run many compatible applications. Standard software included a spreadsheet program, a word processor, a calendar, a to-do list manager, and a communications package. It also had a built-in HP financial calculator, continuing a long tradition for the company. The device was powered by two AA batteries and often featured an optional rechargeable battery pack.

The 200LX was popular among business professionals and students who needed a portable device for note-taking, basic document creation, and data management without the bulk or power consumption of a laptop. Its compatibility with MS-DOS software made it a versatile tool for its era. While eventually superseded by more advanced devices, the 200LX is remembered as a significant step in the evolution of portable computing.
