1940 US New York [USA]

He was the chief architect of the Intel 8086 microprocessor, the first processor of the x86 architecture, which went on sale in 1978, and which served as the basis for its version with a reduced 8-bit bus for the IBM-PC and compatible computers.

Due to the delay in the development of the Intel 8800 processor and the market launch of Zilog's Z80 microprocessor, Morse was assigned to develop an intermediate microprocessor to respond to the Z80 before the 8800 was released.
The 8086 needed to be able to execute the 8080 instruction set at the assembly language level (not machine code), making it easy to convert the code base of the previous processor to run on the new processor.
Logical and arithmetic instructions were expanded from 8 to 16 bits, including multiplication and division, and other instructions such as string instructions were also added.
The ability to handle much more memory than the 8-bit processors of the time was added.
