The HP 200LX Palmtop PC (F1060A, F1061A, F1216A), also known as project Felix, is a personal digital assistant introduced by Hewlett-Packard in August 1994. It was often called a Palmtop PC, and it was notable that it was, with some minor exceptions, a DOS-compatible computer in a palmtop format, complete with a monochrome graphic display, QWERTY keyboard, serial port, and PCMCIA expansion slot. The abbreviation "LX" stood for "Lotus Expandable".
