	Z80 assembler mnemonics

This is the complete Spectrum character set, with codes in decimal and
hex. If one imagines the codes as being Z80 machine code instructions,
then the right hand columns give the corresponding assembly language
mnemonics. As you may be aware certain Z80 instructions are
'compounds' starting with CBh or EDh, these are shown in the two right
hand columns. Where a character changes between 48K and +3 (128K)
modes, the 48K version is given in brackets after the +3 one.
