I'm gonna guess that's more around 1978--that's when I remember biorhythm being the big buzzword...right up there with mood rings and pyramid power....
Do you know of any company that manufactured calculators like Kosmos and Casio that could supply info past 1999??-as Kosmos and Casio could only calculate up to 19999-bummer. Apr 2022. Louis p canada
I'm unaware of any vintage electronic biorhythm calculators that went past 1999. I don't know if that was because of an internal electronic limitation like Y2K or if it was because the charts used in the math had only been developed up to 1999. I'm not sure if the non-electronic biorhythm devices like the Biomate I demonstrated in another biorhythm video had that 1999 limitation.
Interesting....vedio ...thanks very much Sir..
