Here is something I did some months ago. I wanted to release it, but for some strange reason I totally forgot about it
This isn't intended to replace any kind of 68k documentation, it is just a list of opcodes with their format.
I made this because I was tired of always searching Motorola's pdf manual. Actually it cannot replace the manual beacause of the lack of specific information on opcodes but can still be usefull (especially if you have it printed on paper ).
