Best reference for DASM's illegal opcodes?

Another option is to look at DASM's source. This file has illegal opcode mnemonics in an array called Mne6502illegal[], except for the illegal NOP addressing modes (related to what Omegamatrix said). Might be useful since there's not much standardization of the actual mnemonics.
