TI-2000 Time Manager integrated in the sleek housing of the TI-1750-III
a clock, two 24-hour alarms and a stopwatch with 1/10 of one second resolution.
The Time Manager was sold together with its own smoked-acrylic desk stand to do calculations, check time, job notes and appointments at the desk.
Instead the usual 7-segment layout of the LC-Display to build the digits 0..9 the Time Manager added some segments and displays even a limited set of characters.
The printed circuit board (PCB) of the Time Manager gives a rare combination of an Enhanced C-MOS calculator chip of the TP0456 architecture developed for scientific calculators like the TI-55-II and the small housing of the Basic Calculators. Please notice the shrinked housing of the Integrated Circuit (IC) compared to its standard size found e.g. in the LOGpit.
It took another five years before the paper appointment pads were replaced with an electronic memory. Don't miss the Mini Data Bank.
