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 .
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 ...
The P75 was a released in 1990 upgraded version of P70 model, and is noted as being the first portable computer using a 486 CPU to be available for sale in the United States. It had a briefcase-shaped design and ran off A/C power only, as was common with high performance portable computers at the time.
The company's first PC related product was the PC Speeder, a device designed to increase the clock speed (and thereby the performance) of the 8086 processor. The company then began work engineering a motherboard to retrofit the soon-to-be-introduced Intel 386 processor on their existing 286 platform.
All laptops in the LTE Elite range sported Intel's i486 processors, from the 40 MHz DX2 to the 75 MHz DX4. The LTE Elite was the first notebook-sized laptop to house the AC adapter inside the case itself, eliminating the need to carry an external power brick .
The Intel i486SL is the power-saving variant of the i486DX microprocessor. [1] The SL was designed for use in mobile computers. It was produced between November 1992 and June 1993. Clock speeds available were 20, 25 and 33 MHz. The i486SL contained all features of the i486DX.
The PS/ValuePoint (or just ValuePoint) personal computer was IBM's answer to the PC clone market, where the IBM PS/2 could not compete due to price and proprietary interfaces. Announced in October 1992 and withdrawn in July 1995, it was replaced by the IBM PC Series 300 .
