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 ...
8086 first x86 processor; initially a temporary substitute for the iAPX 432 to compete with Motorola, Zilog, and National Semiconductor and to top the successful Z80. The 8088 version, with an 8-bit bus, was used in the original IBM Personal Computer. 186 included a DMA controller, interrupt controller, timers, and chip select logic. A small ...

The 8086-based IBM PC, launched in 1981, started the move to 16-bit, but was soon passed by the 68000-based 16/32-bit Macintosh, then the Atari ST and Amiga. IBM PC compatibles moved to 32-bit with the introduction of the Intel 80386 in late 1985, although 386-based systems were considerably expensive at the time.
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.
Through the addition of the expansion unit, the Model A could therefore be upgraded to the Model B. The core system employed the Intel 8086 processor, aiming for a level of compatibility with the IBM PC, and 128 KB of RAM, expandable to 256 RAM in the system unit and to a total of 768 KB utilising the expansion unit.

Twenty-two-year-old Tim Paterson was hired in June 1978 by SCP's owner Rodney Maurice Brock (26 August 1930 – 30 November 2018). [4] [5] At the time, SCP built memory boards for microcomputers, but after attending a local seminar on Intel's just-released 8086 in late summer 1978, Paterson convinced Brock that his company should design a CPU board for the new chip.
The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive .
