Berra is a number identification device built with IC components during the course ’Digitala Systems, Project Laboratory’. It’s a prototype and due to that it’s built upon a circuit board. Berra can store 50 telephone numbers and 50 names plus telephone numbers in its memory. It has a big display with 4 rows and 16 columns. The current date and time is displayed at the bottom row of the display. When somebody calls, the telephone number, the date, the time and if existant the name is displayed. Its main processor is a Motorola 68008 running at 10 MHz. Among the other components one could find a real time clock and a DTMF decoder/encoder.
