The first [[personal computer]] to make use of the 386 was designed and manufactured by [[Compaq]][http://www.crn.com/sections/special/supplement/816/816p65_hof.jhtml], and [[Andrew Grove|Andy Grove]], Intel's CEO at the time, made the decision to [[Single-sourced|single-source]] the processor, decisions that were ultimately crucial to both the processor's and Intel's success in the market.
 
In May 2006 Intel announced that production of the 386 would cease at the end of September 2007. [http://www.reghardware.co.uk/2006/05/18/intel_cans_386_486_960_cpus/] Although it had long been obsolete as a [[personal computer]] CPU, Intel had continued to manufacture the chip for [[embedded system]]s.

The processor was a significant evolution in a long line of processors that stretched back to the [[Intel 8008]]. The predecessor of the 80386 was the [[Intel 80286]], a [[16-bit]] processor with a [[memory segment|segment]]-based memory management and protection system. The 80386 added a [[32-bit]] architecture and a [[paging]] translation unit, which made it much easier to implement operating systems

===BusinessBisnis importancepenting===
The first PC company to design and manufacture a PC based on the 386 was [[Compaq]], rather than [[IBM]], which had been dominant until that time. IBM was offered use of the processor, but relied instead on earlier processors to which it had manufacturing rights. The success of the Compaq 386 PC played an important role in creating the PC "clone" industry, and to establishing Intel (and [[Microsoft]]) as central component suppliers to it.
 
From a business perspective, the i386 was significant because it was the first significant microprocessor to be [[single-sourced]] – it was available only from Intel Corp. Prior to this, the difficulty of making chips and the uncertainty of reliable supply required that any mass-market semiconductor be [[multi-sourced]], that is, made by two or more manufacturers, the second and subsequent ones manufacturing under license from the designer. Single-sourcing the i386 allowed Intel greater control over its development and substantially greater profits in later years. However, [[AMD]] introduced its compatible [[Am386]] processor in March 1991 after overcoming legal obstacles, thus ending Intel's monopoly on 32-bit 386-compatible processors.
