Gen1 , Gen2...etc , differences.

Sorry for what might be a common question but I don't have much luck with the "search" function. I always get Sorry, No matches found :CRY:

I was looking for a little SBC 101?

How many generations of the sbc are there?

What years were they produced?

What are the differences?

What's the best or most sought after and why?

Thanks for any help,

Thanks Henry!

I started reading the reference you sent and it looks like it has the answers to my inquiry.
