Learning Z80 assembly, are you Rodnay Zaks or Lance A. Leventhal ?
-To learn Z80 assembly, I only knew the book by Rodnay Zaks, but it seems it's not the best one after reading this Twitter thread. So the book by Lance A. Leventhal would be more didactic and less redundant.
These two books are available on Amstrad CPC Mémoire Ecrite, but beware the last edition of the Rodnay Zaks's book is 1982, the one by A. Leventhal is 1983. Don't download an older version. Rodnay Zaks also exists in french, spanish and german (in 1982 and 1987).
