8086 = 8057?

[thcg]

        I sent a previous mail to the listserv with no response... my
question was:

        Are the 8086 instructions compatible with any intel
microcontrollers such as the 8051, 8057 80257 MC80257 etc? If so, very
cool linux machines with LCD displays and cheap MCUs can be build for the
third world :) . Any ideas anyone??
