The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 [citation needed] and June 8, 1978, when it was released. [5] The Intel 8088, released July 1, 1979, [6] 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 ...
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.
It is even possible that the 8086/8088 does not respond to a change in the level of MN/MX after a hardware reset but only at power-up. Even then, it is certainly possible to design hardware that will power down the CPU, switch MN/MX, wait an adequate amount of time, and power it back up. 108.16.203.38 10:01, 9 October 2013 (UTC)
This derived directly from the hardware design of the Intel 8086 (and, subsequently, the closely related 8088), which had exactly 20 address pins. (Both were packaged in 40-pin DIP packages; even with only 20 address lines, the address and data buses were multiplexed to fit all the address and data lines within the limited pin count.)
The 8086 processor has a six-byte prefetch instruction pipeline, while the 8088 has a four-byte prefetch. As the Execution Unit is executing the current instruction, the bus interface unit reads up to six (or four) bytes of opcodes in advance from the memory. The queue lengths were chosen based on simulation studies. [9]

DP Kwazar SP (ДП КВАЗАР-ІС) [6] - As of December 2021, КР1810ВМ86 (Soviet 8086 clone) still appears on Kwazar's price list.

The 50-pin "Benton Harbor Bus" was considered an improvement on the S-100 bus. [15] [16] The 50-pin bus of the H8 contains sixteen address lines, eight data lines, five interrupt lines, and the system control lines. Like the S-100 bus, it does not supply +5 V; each card is expected to have its own local +5 V regulator powered from "unregulated ...
