I came across an old casio calc from the 80s
Its the one with biorhythm calculator on it or it is a fortune telling thingy....
Here is one on ebay https://www.ebay.co....en/133530648850
Have put new batts in but I have no idea how to turn it off or where any instructions are
Cant find anything on the net
It is a combination of button presses ?!
