The 386 was the central processing unit (CPU) of many workstations and high-end personal computers of the time. The 386 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.
The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386 . It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386 .

This unit was made in January 1995, and was taken from a Toshiba laptop. Intel DX4 Overdrive. IntelDX4 is a clock-tripled i486 microprocessor with 16 KB level 1 cache. [1]
The Personal System/2 Model 70 386 and Personal System/2 Model 70 486 are midrange desktop computers in IBM's Personal System/2 (PS/2) family of personal computers. The PS/2 Model 70 386, released in June 1988, features an Intel 386 microprocessor clocked between 16 MHz and 25 MHz (depending on the submodel) and features the 32-bit Micro Channel architecture (MCA) bus; the Model 70 486 ...
C&T also developed a 386-compatible processor known as the Super386. This processor supports, in addition to the basic Intel 386 instruction set, a number of instructions to support the Super386-specific "SuperState V" system-management feature. The added instructions for "SuperState V" are: [7]
An Intel DX2-66 MHz OverDrive An Intel i486SX2-50 MHz OverDrive processor installed next to the original i486SX processor.. Intel's i486 OverDrive processors are a category of various Intel i486s that were produced with the designated purpose of being used to upgrade personal computers.
The i486DX2-66 was a very popular processor for video games enthusiasts in the early to mid-90s. Often coupled with 4 to 8 MB of RAM and a VLB video card, this CPU was capable of playing virtually every game title available for years after its release, right up to the end of the MS-DOS game era, making it a "sweet spot" in terms of CPU ...
As well as being IBM's first 386-based PC, the Model 80 was the company's second Intel-powered PC built into a tower case. [12] The case was identical to the Model 60—IBM's first Intel-based tower computer—down to the carrying handle included on top of the machine, to aid in lifting the relatively heavy computer, at roughly 40 pounds (18 kg).
