A hand computer is a portable lightweight (2kg) level 1 computer fitted with a short wave radio and powered from a power beltpack. The hand computer has the following level 1 programs: analysis, communication, and information storage. The communication program allows it to be interfaced with a larger computer via its short wave radio. Information can be passed freely between two computers over the radio link, allowing hand computer to access far larger amounts of data than it would be able to do with its restricted function point size.
