The TI-1001 is another design of the original TI-1030 calculator. You should compare it with the TI-1031, the ET calculator and the TI-1750-III, too.

The TI-1001 was used as the base calculator for the TI-1850 Visor Kit and the TI-1880 Checkwriter.

This calculator was produced both in Italy and US. Within one year of its introduction the keyboard design was slightly changed, don't miss the second generation of the TI-1001 manufactured in the US and the TI-1001 made in Italy.

Find here an excerpt from the Texas Instruments Incorporated leaflet CL-199J dated 1981:
