This is binary clock, which displays current time (hour, minute and second) in both binary and decimal. You can switch on/off decimal display with A button. This is just for ornamental. If you're interested in this topic, please copy the source on the attached photo by yourself. I'm sorry to give you trouble.
I guess there's no public key? If there was, I could spot it out without translating. It's OK if you didn't upload it. Oh that picture! It only has 29 lines of code? Now I understand what you mean in that last comment. Your saying that if I wanna try this, I should type all of what I see in that picture into my SmileBASIC. OK, thanks.
