[Coco] Starting to unpack COCOs from storage

[John E. Malmberg]

I am just now getting to unpack my COCO stuff and see what I actually have.

Is there a way in ROM basic to detect if a 6309 is installed that would 
work on COCO-1 though 3?

How to detect how much memory is actually in a COCO 3 from basic?

And is there a way to detect if a system is a COCO 1 or  COCO 2?

I saw a mention of www.cocopedia.com wiki, but actual WIKI articles seem 
to be sparse.  Is that intended to be the main web site for the community?
