This is an early (about 1972) small calculator with built-in power supply. It supports the basic arithmetic functions; it has one memory register. The size of the numeric keys is about 15 mm. The display is built from eight vacuum-fluorescent tubes for the numbers plus one combining the overflow indicator and the minus sign. (*).
