Kosmos International, Inc. based in Atlanta, Georgia introduced with the Kosmos 1 already in the year 1977 a pocket-sized biorhythm calculator.
On a first glance you notice the original calculator keypad and the three „sine-waves“ representing our:
|• Physical Cycle (P)
• Emotional Cycle (S)
• Intellectual Cycle (I)
This Kosmos 2 was introduced in 1979 as the successor of the original design and obviously was the result of some cost reduction programs:
|• The 6 red and amber LED's at the end of the three "sine-waves" were omitted
• The housing feels much cheaper
• Manufacturing was moved from Japan to Taiwan

Dismantling this Kosmos
calculator manufactured in September 1979 by Zeny in Taiwan reveals a very well engineered design centered around a Texas Instruments 4-bit single-chip microcomputer.
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 basically an application program running on a TMS1170
microcontroller with 2,048 bytes of ROM and 128 x 4 bits of RAM.

The next product in the Kosmos line is the Astro – the toy of your fortune-teller.
Biorhythms are inherent cycles which regulate metabolism, coordination, emotions, sexuality, memory, and more. We have 3 fundamental biorhythm cycles. Each biorhythm cycle has a particular life span.
Our physical cycle completes one life span (or cycle) in 23 days. The emotional
cycle lasts 28 days, and the intellectual cycle lasts 33 days.
At mid point, and end point in each cycle, the cycle sharply moves back to zero point and changes polarity, thus creating a transition day (also called a critical day, or caution day). That's all there is to it! As each cycles changes polarity, we experience life's ups and downs!
Biorhythm cycles are as follows:
|• Physical Cycle (RED) 23 days
The physical cycle is the dominant cycle in men. It regulates hand-eye coordination, strength, endurance, sex drive, initiative, metabolic rate, resistance to, and recovery from illness. Surgery should be avoided on physical transition days and during negative physical cycles.
• Emotional Cycle (BLUE) 28 days The emotional cycle is the dominant cycle in women. It regulates emotions, feelings, mood, sensitivity, sensation, sexuality, fantasy, temperament, nerves, reactions, affections and creativity.
• Intellectual Cycle (GREEN) 33 days The intellectual cycle regulates intelligence, logic, mental reaction, alertness, of direction, decision-making, judgment, power of deduction, memory, and ambition.
