This Canon card F-32 Mathematic Calculator introduced in 1980 features some rather unusual keys:
|• [ON] in addition to a mechanical ON/OFF Switch
What makes the F-32 really unique is the [DS] key which allows to select the setting of the entry mode:
|• [DS][F] Indicator (--) Floating decimal with manual insertion of the decimal using the [.] key
• [DS][+] Indicator (AM) Add mode with the decimal automatically put in the dollars and cents position (0.00)
• [DS].. Indicator (0)..(4) Fixed decimal display with zero to four digits behind the decimal point (x.)..(x.yyyy)
We recognize this functionality from so-called Checkbook Calculators, compare with the National Semiconductor NS103A Data Checker.
Dismantling the Canon card F-32 reveals consequently a design centered around a NEC uPD1831G
single-chip calculator circuit, a single memory variant of the uPD1833G found in
most Checkbook calculators developed in the 80s.
