Here are all the chapters as of the date at the bottom of this page. A couple of them are still empty and I will try to indicate their degree of completion as I go:
"Done" means "Done for the time being and as far as I can see which is not very far."
"In progress" really means "This is one of the chapters I wish I were working on these days".
I have now filled most of the chapters from "prerequisites" I had to have in RBA and RAF inasmuch as they are standalones. Of course, they need an unknown amount of rewriting.
I also believe that the table of contents is indeed getting there. At least to my eye, it looks a lot better than it did.
I hope that this process will converge but it will be slow and I sure wish I could discuss things with others: talking to myself is not exactly efficient.
I have not uploaded the complete source because it would become obsolete in a very short time but I am of course more than willing to send it to anyone interested. Also, here is the November 30, 2011 source of chapters 1 to 4 (24.6 MB) which, as of January 21, 2012, I don't consider to be stable anymore: I ran into a problem which I will try to discuss in the Underground one of these days.
PART ONE: THE LANGUAGE OF ARITHMETIC
Chapter 2 - Tally Mark Systems Not quite stable anymore as of December 2, 2011. (Internet Explorer seems to have had an intermittent problem with the November 30 upload.)
