I taught myself MSX Basic and Z80 ASM by playing around with sources I typed over from mags and by reading tutorials in the same mags. I took me years, during which I made games and other software, until I found I you could code machine language in a different way than 250 data 3E, AA etc. I remember all opcodes until today as I spent years writing software with those, translating by hand. It was fun though: everything was in front of you; no libraries to install and learn, just trying out and learning tricks to optimize and get better results.
