Litronix 2230 Memory
Brief History
Litronix, one of the strongholds of LED manufacturing, has been assembled pocket calculators since 1973. The second generation of these machines already had Litronix chips. The model 2230 Memory have some unique Litronix features: can be switched on or off with touching a button, and the circled decimal point, which is used to indicate errors or overflow during calculations. To reduce production costs, manufacturing had been relocated to Malaysia, but that could not save the company from merging with the Siemens group, which also meant the cessation of calculator production.
