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
