Good day all!
I just scored 11 desktop calculators. These calculators are older styled, accounting calculators, with ticker tape printers. Large keys, powered by 110VAC.
Before I rip these apart and rob all of the components from them for other projects, does anyone know of any practical things / circuits that I can make with these calculators, besides paperweight, or component source?
Looking at the innards, I see:
1. The ticker tape printer and components.
2. 12 digit LED display.
3. 30 button oversized keypad.
4. A nice sized transformer, unknown value. The calculator UL listing states 120V, 160mA, 16watt. Which is after the power grid.
5. circuit board, mostly power related, transistors, diodes, capacitors, 1.4 resistors etc.
6. Large IC. 64 pins, SC58101-357SP 357-919106.
7. 3 16-pin IC's, IR2411. I think these are for the LED display.
The particular model I am looking at is:
SHARP Compet QS-2760
Any ideas of what I could make of these? Thanks a bunch!
