The Sharp EL-160 was an early desktop calculator produced by Sharp.
Special features
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 (12x Itron DG12B and 1x Itron SP-12A), and 4 Integrated Circuits, the Rockwell MRD2256, DC1152, ACM1156A, AU2271C, and the Hitachi HD3113, presumably for keyboard decoding purposes.
