Hello,
I was searching a few hours now for the 80286 instructions set list on the Inet.
But all the searching resulted in nothing useful.
So I decided to ask you guys to help me, if you have it or know where I can get it...I would like to hear!

If you wonder why I need especially the 80286, because I write a disassembler, and I want to let the user select 16/32 bits,
and the 80286 is the last 16 bits processer in the 80x86 family...

If you have other ideas how I can distinguish opcodes for 16 or 32 bits, so you are more than welcome to tell me about it.

Thanks in advance. :alright:

Great, I will wait for it. Hope your debugger can trace instruction. I build my own assembler here. You can see it on my website, it open source.:alright:

Thanks for the instant replying.
I have HelpPC already, but I am looking for the Intel's original code table/data sheet...

Well realvampire, I develope it for my own fun and profit, I thought it would be a challenge to decode 80x86 instructions, because they are pretty messy, but to be honest it was easier than I thought it would be in first place.
I don't think I am going to make it a debugger... Not interested in it, but I wanna make it a complete disassembler...
supports at least 16/32 bits instructions + FPU...

I will take a look at your web site, seems to be interesting.

Thanks guys.

I searched it too but Intel's original is, as I think, not possible to obtain. Intel's official site no longer offer it.

Try to ask on http://www.sandpile.org/post/

the Intel 80286 Hardware Reference Manual is only in BOOK form
so you can try to find it at a libary lol if it spelt that right..

or buy it from like amazon.com

they have other books also on the other cpus all in one book but its like 110$
