I386
The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor developed jointly by AMD, IBM and Intel. Pre-production samples of the 386 were released to select developers in 1985, while mass production commenced in 1986. It implements the IA-32 microarchitecture, and is the first CPU to do so. It was the central processing unit (CPU) of many workstations and high-end personal computers of the time. It began to fall out of public use starting with the release of the i486 processor in 1989, while in embedded systems the 386 remained in widespread use until Intel finally discontinued it in 2007.
