Info:
Kosmos International, Inc. based in Atlanta, Georgia introduced already in the year 1977 this pocket-sized biorhythm calculator. On a first glance you notice the [BIO] key on the calculator keypad and the three „sine-waves“ representing our:

• Physical Cycle (P)
• Emotional Cycle (S)
• Intellectual Cycle (I)

• 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
