This Canon card quartz LC-64T followed the LC-61T and added once again useful features into a credit card sized housing. The specification of the calculator include now:
|• 8-digit calculator including full memory
• Clock with alarm time and buzzer
• Calendar with Day of Week function
• Stopwatch with intermediate results
• Conversion capability (multiplies with and divides by a constant)
The Calendar includes a readout of the "Day of Week" in the upper part of the LC-Display. The conversion capability could be used for either tax calculation, currency conversion and even time conversions by simply writing the conversion constant into the dedicated "S-memory" and performing both multiplications and division with a single keystroke.
Please notice that Texas Instruments used the same Toshiba T6798S single-chip calculator circuit with their TI-1788 III and added one extra [WT] key to view the World Time.
