On a first glance you notice the original calculator keypad and the three „sine-waves“ representing our physical cycle (P) , emotional cycle (S) and intellectual cycle (I). Get more about the biorhythms here.
At the second moment you’ll ask yourself:
Is there any relation to Texas Instruments ?
Texas Instruments invented the microcomputer and introduced in the year 1974 with the TMS1000 the first commercial product. The TMS1001 was the first LSI MOS chip of the TMS1000 family used in the Texas Instruments SR-16 calculator. The chip contains a microcomputer complete with a program ROM having 1,024 eight-bit words; a temporary storage RAM; input (from keypad); output (to control keypad scan and LED display); and an oscillator (clock). Within the next months a lot of variants of the TMS1000 appeared, including display driver, higher memory capacity and more input/output connections.This Kosmos 2 biorhythm calculator is just an application program of a TMS1100 microcomputer ! The next product in the Kosmos line is the Astro – the toy of your fortune-teller.
