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
