Thanks to e5frog, whom spotted several pages that needed some fixes, this version 3 -and hopefully final- is now replacing the one released a few days ago.
Do enjoy this one as 7+ hours post-scanning has been put into making this pdf.
The C64 Programmers Reference Guide has been updated. it’s now 600dpi, was 300dpi, now around 95megs in size, before 260megs. and the frontpage colors has been corrected.
