They mentioned Z80 but do not have the examples of Z80; maybe in future might be added. I have used some assembly language stuff, including 6502, Knuth's MIX and MMIX, and virtual codes such as Z-code and Glulx. I have written small amounts of old x86 assembly code (for the older 16-bit PC), too. (I think that the new x86 is too messy and too complicated, compared with the old x86 which is not bad.) I have been trying to learn TRON assembly code too, although I cannot find enough information. I found some documents, but they are in Japanese and some important diagrams seem to be missing. There is some English documentation too but it does not explain much.
