Texas Instruments TI-71 Clock

This TI-71 electronic digital clock with its bright LED-display was introduced by Texas Instruments together with its sibbling TI-70 already in 1974. While the TI-71 sports an alarm function, is the TI-70 a bare digital clock.

Both digital clocks rely on a pre-programmed TMS1000 series 4-bit microcontroller known from calculators like the SR-16. 

Texas Instruments sold the TMS1000 familiy into different applications:

The TMS1117 is a microwave oven controller that's also useful as an industrial timer. And the TMS1018 is a number cruncher.

In one product Texas Instruments used a clock chip from their competitiors, read more about the TI-3510.
