The display of the PS-2400 consists of one line for alphanumeric characters and one line supporting only numbers. The PS-2100 packaged the same specifications in a credit card sized housing. A more powerful Databank was introduced in the same year with the PS-3600. A similar housing was used even for a Translator, don't miss the PS-5400.

The PS-2400 roots back to the Mini Data Bank introduced in the year 1987. This powerful Databank stores 150 names and numbers in a single-chip microcontroller! The same chip scans the keyboard and drived the dot-matrix keyboard. Any ideas about other products with this hardware? Don't miss the Galaxy 67 !
