Hi,
Can some one point/send me a complete list of opcodes  68000 processor
I have the programming manual. But I am not able to find the equivalent codes
of my disassembled file.
for example 31fc, 5278...

Thanks
Edison

If you have the one from Motorola, it gives you the bit-level format
for each instruction. Simply do a trivial binary -> hexadecimal
conversion.

i never seen a list about the opcodes. maybe google helps!

but your example is a move absolut: 'move.w $5278,$38.w'

if you will work with 68k processors, the more easy way is buy
an old m68k machine, like an amiga or macintosh, put linux or netbsd
and use objdump. for example, liquid.rom is a binary image with
startup code in 0x4000:

        # objdump --disassemble-all --target=binary --architecture=m68k
--start-address=0x4000 liquid.rom

        liquid.rom:     file format binary

        No symbols in "liquid.rom".
        Disassembly of section .data:

        00004000 <.data+0x4000>:
            4000:       4e71            nop
            4002:       2e7c 0010 0000  moveal #1048576,%sp
            4008:       2c7c 000f f000  moveal #1044480,%fp
            400e:       4e66            movel %fp,%usp
            4010:       207c 10c0 0000  moveal #281018368,%a0
            4016:       227c 0000 0000  moveal #0,%a1
            401c:       203c 0000 ffff  movel #65535,%d0

            4024:       51c8 fffc       dbf %d0,0x4022

            ... etc ...

fast and easy!

Why port an OS and run objdump there?

GNU binutils can be easily built as cross-tools, running on Linux/i386,
Windows (using cygwin) etc. - then simply run m68k-<whatever>-objdump on
your normal development machine!

<whetever> will usually be coff or elf.

1. request online list of opcodes for 68K processors

 Could someone kindly post / email-me a list of opcodes for the 68K
 (68040 would be optimal). I am looking for no great detail, just a
 list defining the instructions - though lot's of detail would be
 welcome. I am looking for an _online_, handy reference.
