Specs: Windows XP, 2 GB
Hi
I am looking for a full documentation of the Intel 8086 processor, without any instructions from newer processors, have searched the web and not found what I'm looking for.
Could you please help?

Sorry, I have already seen that list, but the key thing is missing: it doesn't have opcodes.
I am trying to make a disassembler, so I need the bit arrangement and opcodes to decode the instructions.
I think Intel might have a manual for programming with the 8086/8088 but have not been able to contact them.
Thanks

Google "8086 opcodes". Here's a listing of the opcodes for all the x86 processors.

Of course you could just assemble the instructions and see what opcodes they produce.
