The Sharp EL-160 was an early desktop calculator produced by Sharp.

Special features

Since the calculator uses the Itron font tubes it does not feature leading-zero supression, to help with readability (e.g. it would display '00000001' to display '1').

The calculator uses separate 'minus equals' and 'plus equals' keys, as well as a single key for multiplication and division, this was common for the time period.

The calculator also has an 'm/d' key, this allows the user to switch between having an 8 digit memory and having an extended 16 digit multiplication/division results register.

Internal design

The calculator uses 3 PCBs internally, one for the power supply, mounted inside a metal cage, and display and logic boards, both seated into a card-edge connector.

The calculator uses a reed-switch keypad, Vacuum Fluorescent Displays (8x Itron DG12B and 1x Itron SP-12A), and 5 Integrated Circuits, the Rockwell NRD2256, Rockwell DC1152, Rockwell ACM1156, Rockwell AU2271, and the Hitachi HD3113, presumably for keyboard decoding purposes.
