Abstract
A portable electronic dictionary with a micro-computer in a hand-held housing which mounts a plurality of alpha-numeric displays and a keyboard. A plug-in ROM stores a plurality of pairs of sequences of alpha-numeric characters and is searched by a central processing unit in the micro-computer under instructions stored as firmware in another ROM forming part of the micro-computer. 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 micro-computer until a match is found. After one or more sequences have been entered into the keyboard and locations of matching pairs stored in the micro-computer 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.
