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 TI-1001 was manufactured in August 1982 in Abilene, Texas and sports a slightly different keyboard design compared to the original TI-1001.

Dismantling the calculator reveals a well-known design identical to the original TI-1030 and still using the TP0311 first generation single-chip calculator circuit based on the TMS1000 Microcomputer family.

The TI-1001 calculator was built both in Italy and US, the European TI-1001 seems to be identical with the US model.

Don't miss the TI-1002 introduced already in 1983.

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

TI-1001

Economical, pocket-portable, six function calculator.

Almost everyone in the family can use it - around the house, in class, at the office - even outdoors. Sleekly styled, lightweight, thin as a pencil. Fits easily into a pocket, purse or brief case to go where you go.
Get fast, accurate answers to addition, subtraction, multiplication and division problems. Even square roots. A percent key automatically calculates percentages. Automatic constant feature eliminates the need to reenter a number in repetitive calculations.
TI’s APD* automatic power down feature helps prevent accidental battery drain by turning off the calculator after approximately four minutes of non-use.
