The HP-110, HP's first laptop computer, was an industry breakthrough. Weighing 8-1/2 pounds, this notebook-size computer had a 16-bit IBM PC-compatible processor. With 384K ROM and 272K RAM, the HP-110 had the largest amount of memory available in a portable computer when it was introduced. Because it ran MS-DOS, it could be linked with an IBM PC or the HP-150 touchscreen computer. Aimed at less technical users than the HP-85 or the HP-75 computers were, it cost $2,995.
