Same here. The ZX manual that came with a list of Z80 opcodes was how I learnt assembly/machine code programming. I lived in a real backwaters, and getting the ZX Spectrum as a gift from a distant uncle changed my life. Had no other books, no community, absolutely no other resources to learn anything.
