ABSTRACT:
A portable electronic dictionary in a hand-held housing which mounts a plurality of alpha-numeric displays and a keyboard. A plug-in module contains a microcomputer and a ROM which stores a plurality of pairs of sequences of alpha-numeric characters and is searched by a central processing unit in the microcomputer under instructions stored as firmware in another ROM forming part of the microcomputer. One sequence of each stored pair is compared with a sequence which is entered into the keyboard and stored in a RAM also forming part of the microcomputer until a match is found. After one or more sequences have been entered into the keyboard and locations of matching pairs are stored in the microcomputer RAM, the pairs of stored sequences can be rolled across the display. Either sequence of each pair can be compared with a sequence entered into the keyboard.
