HP_Portable_Plus
The Hewlett-Packard HP 110 (aka HP Portable and HP 45710A) is an MS-DOS compatible portable computer released in 1984. It uses a Harris 80C86 running at 5.33 MHz with 272 KB of RAM. It has an 80 character by 16 line monochrome (480 x 128 pixel) liquid crystal display, runs MS-DOS 2.11 in ROM, and has the application programs MemoMaker, Terminal Emulator and Lotus 1-2-3 in ROM.[1]
The LCD can be tilted for visibility, and can be folded down over the keyboard for transport, unlike computers such as the TRS-80 Model 100 which has the display in the same fixed plane as the keyboard. The HP 110 is similar to the Dulmont Magnum and the Sharp PC-5000, but all three computers were separately developed by their respective companies. At introduction it had a list price of 2995 US$ (today $8780).
