DATAMATH CALCULATOR MUSEUM |
Texas Instruments invented the integrated circuit (IC) in the year 1958 and developed only 10 years later with the Cal-Tech project the first portable electronic calculator. With the TMS1802 in the year 1971 the next important step happened, TI released the first commercial available "calculator-on-a-chip" circuit. Get the original press release here. Within the next six years Texas Instruments developed a lot of powerful calculator chips, find a list of all known chips here. Around the year 1976 they lost the race! Many Japanese companies like Sharp, Casio and Toshiba introduced small calculators using a modern LCD-display instead the power hungry red LED-displays. Combined together with new calculator chips produced with a C-MOS process the calculators worked some 1000 hours on two small coin batteries. It took a long time until Texas Instruments introduced April, 1977 with the TI-1750 their first LCD-calculator. And this calculator was based on a Toshiba chip! Few month later TI switched with the TI-1030 back to an US-design but the game was played again and again: The first scientific LCD-calculator (TI-25), the first solar calculator (TI-1766) and the first scientific solar calculator (TI-30 SLR) were all based on Toshiba circuits. And don't forget the wonderful TI-66, a Toshiba designed product, too.
Find some Toshiba calculators here.
It is difficult to get information about the calculator circuits manufactured by Toshiba. The following table gives an overview of the known circuits, a brief description and the calculators using them. Most of the designs base on the Toshiba 4-bit CPU-kernel TMC17A, TMC17C or the (TMP04xx).
Find a short comparison of the Texas Instruments TMS1000 and the Toshiba TMP04xx microcontroller:
