It was marketed for educational purposes in the teaching of the microprocessor systems of the time, and defined by the manufacturer itself as a Nanocomputer (the term was a registered trademark). The primary interface is a hexadecimal keypad with a built-in 8-segment seven-segment display, connected to the main block via a flat cable. For testing with electronic circuits, the NBZ80-S version was offered, including a special hardware for experiments.
