LIST OF OPCODES FOR THE MC68000 PROCESSOR by Richard Karsmakers

Finally!  I thought it would take ages before someone would  come 
up with a full list of opcodes for the 68000 processor,  but Hans 
de Lange recently supplied me with one,  for which I hereby would 
like  to  thank  him  very  much.  Now,  everyone  can  use  this 
information in future times!

Remarks to this list:

This  is  only a simple list,  that doesn't include  clock  cycle 
times,  etc.  'e' means a bit of the effective address field, 'd' 
is  an  offset  bit and 'x' stands  for  further  variable  bits. 
Numbers  preceeded  by  '$' are given  in  hexadecimal  notation. 
Please  refer to our Machine Language course for the  meaning  of 
individual instructions and addressing modes.
