Information on HP200LX?

The HP 200LX is a personal digital assistant introduced by Hewlett-Packard in 1994. It was one of very few palmtops ever developed that was, with some exceptions, 100% MS-DOS compatible. Input was entered via a very small QWERTY-keyboard with a numeric keypad, enclosed in a clamshell-style case, about 25% of the size of a standard notebook computer. The palmtop runs about 30 to 40 hours on two size AA alkaline or Ni-Cd cells and can charge batteries via a 12V DC wall adapter.
