Editing Intel 8086 (section)

===Derivatives and clones===
Compatible—and, in many cases, enhanced—versions were manufactured by [[Fujitsu]],<ref>Intel Corporation, "NewsBits: Second Source News", Solutions, January/February 1985, Page 1</ref> [[Harris Corporation|Harris]]/[[Intersil]], [[Oki Electric Industry|OKI]], [[Siemens]], [[Texas Instruments]], [[NEC]], [[Mitsubishi Electric|Mitsubishi]], and [[AMD]]. For example, the [[NEC V20]] and [[NEC V30]] pair were hardware-compatible with the 8088 and 8086 even though NEC made original Intel clones μPD8088D and μPD8086D respectively, but incorporated the instruction set of the 80186 along with some (but not all) of the 80186 speed enhancements, providing a drop-in capability to upgrade both instruction set and processing speed without manufacturers having to modify their designs. Such relatively simple and low-power 8086-compatible processors in CMOS are still used in embedded systems.

The electronics industry of the [[Soviet Union]] was able to replicate the 8086 through {{citation needed-span|both [[industrial espionage]] and reverse engineering|date=October 2013}}. The resulting chip, [[K1810VM86]], was binary and pin-compatible with the 8086.

i8086 and i8088 were respectively the cores of the Soviet-made PC-compatible [[EC1831]] and [[EC1832]] desktops. (EC1831 is the EC identification of IZOT 1036C and EC1832 is the EC identification of IZOT 1037C, developed and manufactured in Bulgaria. EC stands for Единая Система.) However, the EC1831 computer (IZOT 1036C) had significant hardware differences from the IBM PC prototype. The EC1831 was the first PC-compatible computer with dynamic bus sizing (US Pat. No 4,831,514). Later some of the EC1831 principles were adopted in PS/2 (US Pat. No 5,548,786) and some other machines (UK Patent Application, Publication No. GB-A-2211325, Published June 28, 1989).
