Canon 130S Desktop Calculator |
 | | The Canon 130S is a refinement of Canon's first-generation electronic calculators, which included the Canon 130, the Canon 151, and the Canon 161. |
| | The 130S does not have a "power-on" clear function, which means that when the machine is first turned on, "garbage" may be contained in the machine's registers, and its logic state may be undefined. |
| | The 130S indicates overflow a red-colored left-pointing arrow. |
