for indication of memory content and negative number.

STMicroelectronics W994A microcontroller, both made in 1992. |
||
| Remarks: | The working voltage indicated on the label is 115v but the original seller told me he never took in consideration the voltage... just he plugged it into a standard 220v ac plug and it worked fine... I noticed this in other Olivetti calculators sold in Argentina like my Logos 400aPD, probably made for foreign markets and reconverted to 220v with no change on labels. | ||
