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