are familiar with the design of this rare Number Beat? It is nothing else than
a design variation of the TI-1103 and TI-1104
calculators known since 1986.
Texas Instruments introduced with the Personal Advisorô in 1987 a datebook with advice from 52 celebrities. Please remember Bette Midler, Cindy Lauper, Michael Jackson, Bruce Springsteen, Brooke Shields, Bob Geldof, Tina Turner, Martina Navratilova, Tom Hanks and other stars from the 80's. The package included not only the datebook but even the Number Beat calculator.
Dismantling this Texas Instruments Number Beat manufactured in June 1987 by Inventec Corporation in Taiwan reveals a clean design centered around an unknown single-chip calculator circuit soldered on a double-sided printed circuit board (PCB) and powered by a small LR43 battery.
Inspecting the PCB of this Number Beat calculator brought our attention to a small mark reading IOTI1103A-01A and we started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
