Well, my first project was to replicate something I saw somewhere: connect a pen to a potentiometer and to the serial port of an Apple II in such a way that you could replicate the movement of the pen on screen and also draw.

Apple II . Mouse, touch screens, tablet, etc didn't exist.
It worked.

However, a part from feeling old, I feel also stupid now, because I didn't understand at all the potentiality of such a tool nor what was going to happen in few years.

I could have invented a mouse. Or the concept of GUI. It was just in front of me.

Instead, I think I just draw some tits an some dick.

So I'm here.
Wondering, what is there now in front of my eyes, that I don't see?
