Why is plus on top?

[Batz Goodfortune]

Y-ellow Grant 'n' y'all.
	This always got right up my nose as well. I think more than a few people
have been confused or even tried to challenge the convention over the years.

One of which was a book called. "beginner's guide to transistors." by one
J.A. Reddihough. First published 1968 by Newnes Books. The book from which
I learnt my dubious knowledge of transistor circuits.

Most of the circuits in it are actually drawn upside down to which we know
them today. With negative at the top. Or in other words. Ground at the
bottom with a negative supply. No wonder I had a confused child hood. He
does actually talk about the flow of holes as opposed to electrons though
and his circuits make a lot of sense. until you try to understand more
modern "up the other way" circuits. In which case your brain will probably
try to strangle it self.

Some of the circuits indeed have positive at the bottom labeled as such.
And it's pretty strange seeing people trying to read the book upside down.
I don't know if he was purposefully trying to challenge the convention or
not but it suggests that even in 1968, the convention wasn't quite set in
stone.

Hope this helps.
