ABSTRACT:
An electronic calculator utilizing a programmable read-only memory (PROM) cartridge for control of a number of the calculator functions is provided with a bezel which is snap-fit into a keyed opening in the calculator housing and guides a connector on the cartridge into simple and reliable electrical connection with a connector in the calculator. The bezel, which is simply and inexpensively constructed of plastic, has at least one bevelled outer surface to insure proper orientation of the bezel in the keyed opening and has at least one bevelled inner surface which cooperates with a corresponding bevelled outer surface on the cartridge to prevent improper orientation on the cartridge during insertion thereof into the bezel. The cartridge cover is also simply and inexpensively constructed of plastic, has self-aligning parts, and may be assembled by using a single screw.
