Just wanted a page to accumulate links for people wanting to rekindle their c64 programming skills :)

• https://archive.org/details/Commodore_64_Programmers_Reference_Guide_1983_Commodore
• https://archive.org/details/commodore_c64_manuals

• https://usborne.com/browse-books/features/computer-and-coding-books/
  • Search for the heading “Usborne 1980s computer books”

As the books may make use of PETSCII characters, you might want to consider adding petscii character stickers onto your USB keyboard:
