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.

Internal design

The calculator uses 2 PCBs internally, one is the logic board, and the other is for the display and power supply, both seat into a card-edge connector mounted to the keypad assembly.

The calculator uses a reed-switch keypad, Vacuum Fluorescent Displays (8x Itron DG10: and 1x Itron SP-8A), and 4 Integrated Circuits, the Rockwell DC1152, and the NRD2256.
