I386

The Intel 386, originally released as the 80386 and later renamed i386, is the first 32-bit processor in the line, marking it a significant evolution in the x86 microarchitecture. It 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…
