The Intel 80386 ("eight-oh-three-eighty-six"), also known as i386 or just 386, is a 32-bit microprocessor introduced in 1985. The first versions had 275,000 transistors and were the CPU of many workstations and high-end personal computers of the time. As the original implementation of the 32-bit extension of the 80286 architecture, the 80386 instruction set, programming model, and binary encodings are still the common denominator for all 32-bit x86 processors, which is termed the i386-architecture, x86, or IA-32, depending on context.
The 32-bit 80386 can correctly execute most code intended for the earlier 16-bit processors such as 8088 and 80286 that were ubiquitous in early PCs. (Following the same tradition, modern 64-bit x86 processors are able to run most programs written for older x86 CPUs, all the way back to the original 16-bit 8086 of 1978.) Over the years, successively newer implementations of the same architecture have become several hundreds of times faster than the original 80386 (and thousands of times faster than the 8086). A 33 MHz 80386 was reportedly measured to operate at about 11.4 MIPS.

[Recorded: January 26, 2009] Under the leadership of Andy Grove and Gordon Moore, the personal computer market changed in October 1985 with the launch of the Intel 80386 microprocessor. Today, no one will dispute that Intel is a world-leading company, but few recall that Intel's path to becoming a technology giant was solidified by an unprecedented business strategy. In this lecture Harvard Business School Professor and CHM Board Member Richard S. Tedlow presents and reviews Intel's sole-source supplier business strategy. Learn how Intel forever changed the landscape of the computing industry with its decision in the mid-1980s to act as the sole source for its revolutionary 80386 microprocessor. Prior to this risky and unorthodox move, companies would second-source products by licensing ...

This is basikly my oldest laptop, if you guys like these kinds of videos, i will make more showing some more computers from my colection, witch is rather big. this laptop uses a Intel 80386 Prossesor, and has something around 4 MB's of RAM It used to run on MS DOS 6.22 but the harddrive was damaged and i dont have a replacement.
