 		 #88952 - There's the catch!
Responding to: ???'s previous message
Oleg Sergeev said:
By the way, I have found 8051 manufacturer named "Winedge" which produces very exotic derivative Ultra51TM. I called it "exotic" because this derivative has some additional instructions...
Keil does not support this derivative as well.

That, of course, is the catch.

As I keep saying, the big advantage of the 8051 architecture is that any 8051 tools can be used to create code for it because they all share exactly the same instruction set.
As soon as you start messing with the instruction set you lose that completely, and start requiring device-specific tools - like the PICs?
