This was the tersest possible listing of opcode mnemonics :/
I cobbled together a basic understanding from various machine code listings (Toni Baker, Your Sinclair IIRC), and my "assembler" was paper, pencil and a FOR/INPUT/POKE loop...
My uncle loaned me a Sharp MZ700 one summer, its manual had a detailed breakdown of Z80 opcodes (in mere 4 pages) which was a revelation to me, and an annotated monitor in assembler.
