Summary

[edit]
Description
English: The Canon Pocketronic is the first "handheld" battery-powered printing electronic calculator. The Pocketronic was also one of the earliest calculators to use Large Scale Integrated (LSI) Circuits. No display, printout on thermal paper tape. A total of three LSI circuits made by Texas Instruments was necessary to do the four basic calculations with numbers of 6 to 12 digits.
