Ok they curiosity kills the cat… so here goes…
Can someone explain what P-N-P junctions/diodes do and how that converts into or and logic gates and etc…
Yes I should really read a text but then how would I know that you know

… Plus I am sure one of you could make it easier and shorter then the textbook.
I gave the working of semiconductor diodes in a thread in general once. How that converts into gates… eeekhh thats a yucky topic. too long to type as well (and will have to look at the book for circuit diagrams as well)
one a person gets a hold on np and pnp junctions and working transisters and diodes they should visit:

the definitions are pretty good if you have the time :-/
