Kosmos Bio-Clock (1978)

Here's a rather involved piece of electronics from around 1978 that goes into the pseudo-science of biorhythms. I've made several videos about various biorhythm calculators including one about a handheld Kosmos similar to this desktop unit: https://youtu.be/q3dOrl7KuK4
I don't place any stock in biorhythms but I do enjoy the electronics that were developed for them.

In this video I make use of a manual I downloaded from PreservationSound.com: https://www.preservationsound.com/2019/01/fairly-o-t-the-1978-kosmos-bio-clock-full-manual-download/
