Calculator Technical Information
Updated September 3, 2007.
Welcome to the calculator technical information web site. The primary
purpose of this site is to disseminate information about the internal workings of our
classic and not so classic handheld electronic calculators.
Help me! This web site was born out of the frustration of not being
able to find basic technical information about the chips used in many of the old handheld
calculators, information which can assist with fixing classic calculators. Please help me
find additional technical information on the old calculators, information which can be
put on this web site for others to access.
Thanks, Mike Sebastian
regarding use of information on this web site.
On the web since January 2, 2000.
