:Emacs.
:Anyway, what you've got so far is not particularly clear, and doesn't really present the important information. I'm thinking of a series of tables something like this:

{| border="1" cellpadding="2"
! Oct !! Hex !! Instruction !! States !! Clock !! S !! Z !! X !! H !! Y !! P !! N !! C
|-
| 100 || 40 || ld b, b || OCF(4) || 4 || - || - || - || - || - || - || - || -
|-
| 101 || 41 || ld b, c || OCF(4) || 4 || - || - || - || - || - || - || - || -
|-
| 102 || 42 || ld b, d || OCF(4) || 4 || - || - || - || - || - || - || - || -
|-
| 103 || 43 || ld b, e || OCF(4) || 4 || - || - || - || - || - || - || - || -
|}

:A quick reference for people who actually know what they're doing. For those who don't, these tables should of course be accompanied by detailed descriptions of what the various opcodes actually do.
:Any comments before I go and waste a few hours wikifying the rest of the Z80 instruction set?
:Please don't use parentheses for anything other than indirection!

::Is providing an octal representation actually useful for anything?

btw, sorry about not looking up what the actual value of the hook ptr is
