Looking for Intel Opcodes for writing a disassembler

[jsbenjam]

Hi! I am senior at an University and I'm working on a independent project (not graded or anything). I am trying to write my own disassembler.  I have downloaded the intel manual and some other resources looking for intel opcodes. Does anyone know of a chart or list somewhere with this kind of information?
Example:
note: xx means=1 byte of address or other undefined data

Instruction           Opcode       Operand                 Total Bytes
===========================================
mov esi,al            8A               06                               2
mov eax, esi        8A               0F                               2
call offset         E8              xx xx xx xx                       5

Any help would be greatly appreciated.

Thanks

you mean like that ?
there are a few opcodes you may have to supplement a little - it is an old doc
