Description:

The “calculator-on-a-chip” is a metal oxide semiconductor (MOS) integrated circuit announced by Texas Instruments in September of 1971. A variation was sold in the early handheld electronic calculators of companies like Bowmar, as well as in TI's first portable calculator, the Datamath, introduced in September, 1972.

According to a press release issued at the time of the donation in 1975, the device provided the equivalent of some six thousand transistors.
