Data Corp introduced in 1984 with the Data Dimensioner ® an innovative
product to calculate with mixed dimensions such as feet, inches, fractions and
convert them to their metric or decimal equivalents.
We know a lot of customized products for various applications based on the TI-58 with its unique Solid State Software Modules™ storing up to 5000 program steps, but the Data Dimensioner goes even a step further. Architectural Data Corp replaced the complete electronics of the TI-58C calculator and swapped the power hungry LED-Display with a then state-of-the-art LC-Display with two lines and alphanumerical font.
Dismantling this Data Dimensioner manufactured early in 1985 reveals a printed circuit board (PCB) with roughly the size of a standard TI-58C calculator but only two integrated circuits and a few discrete components.
Main components on the PCB are a Texas Instruments single-chip microcontroller with the markings ADC1984C and C11202NL supported by a standard LCD driver NEC uPD7225G.
Architectural Data Corporation of Louisville, KY
