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.
