32768 a number I remember well. It was the location of the first character on a Commodore P.E.T display.
POKE 32768,65
would put an A there
It's actually 2^16 so the 16th address line on a 6502
65 being the ASCII code for A
It sounds like there must be some sort of clock inside these SSDs because why else would it be counting hours. Also perhaps it's supposed to die when that number runs out but it was either supposed to be a bigger number or a slower count.
