Bob, it's certainly true that it's hard to get your mind around the system. And most of the people here have done it by brute force coding over a period of many months. No one's been able to exactly write the whole thing up because the coding is going hot and heavy.
So instead of demanding that people answer a really broad and frustrated question, how about telling us what you are looking to do and what you want out of a system. And then people are more apt to give you a direct answer.
As far as getting the older code, there is something called CVS...
