Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, [5] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM PC design.

x86 (also known as 80x86 [3] or the 8086 family [4]) is a family of complex instruction set computer (CISC) instruction set architectures [a] initially developed by Intel, based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
The SDK-86 (system design kit) was the first available computer using the Intel 8086 microprocessor. It was sold as a single board kit at a cheaper price than a single 8086 chip because Intel thought that the success of a microprocessor depends on its evaluation by as many users as possible.
Version 4.0 of OMF for the 8086 family was released in 1981 under the name Relocatable Object Module Format, [6] [3] [4] and is perhaps best known to DOS users as an .OBJ file. Versions for the 80286 ( OMF-286 ) [ 7 ] [ 8 ] and the 32-bit 80386 processors ( OMF-386 ) [ 9 ] [ 10 ] [ 3 ] were introduced in 1981 and 1985, respectively.
Case buttons including turbo button The LED display showing the CPU clock frequency, in MHz, of an Intel 80486 based computer. The turbo button is the small button below the segment display; the amber light above is a secondary indicator of the turbo button state.
The Intel 8086, the original x86 processor, is a non-strict extension of the 8080, so it loosely resembles the original Datapoint 2200 design as well. Almost every Datapoint 2200 and 8008 instruction has an equivalent not only in the instruction set of the 8080, 8085, and Z80 , but also in the instruction set of modern x86 processors (although ...
