Architectural
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
TMS70C20 single-chip
microcontroller with the markings ADC1984C and C11202NL supported by a standard
LCD driver NEC uPD7225G.
Architectural Data Corporation of Louisville, KY
is listed as of November 2014 as a manufacturing company for "Electronic, Electrical Equipment
& Components, Except Computer Equipment Companies".
