With the book at the printers, I got my first weekend of "not thinking about the book" since 26th July 2021, when we first launched the campaign.

So, with my second weekend off, I created a short list of facts about the book and process itself.

4 : Most covered number, with nine separate entries
4 : Proof runs - me, to them, to me, to them, to me ...
11 : Number of appendices, labelled 0 to 4294967295
14 : Secret entries, unlisted in the contents
29 : Letters in the longest word of the book
49 : Favourite machines covered (taking over a month to write up!)
58 : Lines of BASIC in an exclusive type-in game
77 : Days between being 100% funded, and my first draft
160 : Entries in contents
185 : Days between launch of crowdfunding, to 100%
576 : Pledges to hit the target
814 : Current number of supporters!

So far, I've only seen the PDFs, but if the printed version matches then there are some very nice tie-ins of page numbers and entry numbers!
