YouTuber “8-Bit Show And Tell” has published a video on the Commodore 8-bit manual “The Complete Commodore Inner Space Anthology” by Karl Hildon (March 1985), editor of the Transactor magazine. (This is actually the first time, I’ve ever heard of this book.) Lots of comprehensive charts regarding the PET, VIC-20, C64, C+4/C16, and an appendix for the C128 (which was just released at that time).
