The HP 110—also referred to as the HP Portable or HP 45710A—is a battery-powered laptop compatible with MS-DOS, introduced by Hewlett-Packard in May 1984. It is equipped with a Harris 80C86 CPU running at 5.33 MHz and contains 272 KB of RAM. The system features a monochrome liquid crystal display capable of showing 80×16 characters, operates on MS-DOS 2.11 stored in ROM, and includes pre-installed software such as MemoMaker, Terminal Emulator, and Lotus 1-2-3.
Distinct from contemporaries like the TRS-80 Model 100, the HP 110 offers an LCD screen that tilts for enhanced viewing and folds down over the keyboard for portability. Although it shares design elements with models like the Dulmont Magnum and Sharp PC-5000, each was developed independently. At its initial release, the device was priced at , which is roughly equivalent to $ in today's currency.
HP 110 Plus
In 1985, Hewlett-Packard introduced the HP 110 Plus (also known as HP Portable Plus or HP 45711A), which featured an upgraded internal modem supporting 1200 baud instead of the original 300 baud. This version also offered additional built-in applications, a lower price point, and an enhanced display capable of rendering 80×25 characters, improving compatibility with desktop software. Users could select between a variant of the HP Roman-8 character set ("HP mode") or IBM code page 437 ("ALT mode") for character encoding.
Reception
In its January 1985 issue, BYTE magazine acknowledged the HP 110's high cost but emphasized its "genuine desktop functionality and performance," particularly praising its keyboard quality and integrated Lotus 1-2-3 software as significant advantages.
Creative Computing described the HP 110 as "the clear leader" among notebook computers in 1984 for users unconcerned about budget constraints, highlighting its robust hardware, comprehensive software package, and strong manufacturer backing despite a $2995 price tag.
