The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture.

The 386SLC is an Intel -licensed version of the 386SX (32-bit internal, 16-bit external, 24-bit memory addressing), developed and manufactured by IBM in 1991.

The Deskpro 386 is a line of desktop computers in Compaq's Deskpro range of IBM PC compatibles. Introduced in September 1986, the Deskpro 386 was the first personal computer to feature Intel 's 32-bit 80386 microprocessor.

Compaq beats IBM to the market when it announces the Deskpro 386, the first computer on the market to use Intel´s new 80386 chip, a 32-bit microprocessor with 275,000 transistors on each chip. At 4 million operations per second and 4 kilobytes of memory, the 80386 gave PCs as much speed and power as older mainframes and minicomputers.

Jun 7, 2017 · Discover why the Compaq Deskpro 386 took the leadership of the IBM PC industry away from IBM in 1986, and how it enabled Linux and Windows NT.

Nov 1, 2013 · Intel introduced the 386SX CPU as a bridge between the generation machines built around its aging 16-bit 286 chips and the more full-featured, state-of-the-art 32-bit 386 processor.

Although the 386DX was a full 32bit chip, most of the early ones were saddled with the IBM AT's 16-bit expansion bus. There were quite a few proprietary buses, before a large group got behind the EISA bus.

Jan 8, 2024 · IBM was late to the 386 PC party, but when they finally arrived they made a statement about what they thought the future of computing would be. With a 32-bit Micro Channel bus and room for six drives IBM aimed this tower directly at the likes of Compaq.

Jun 30, 2023 · The Compaq Deskpro 386/16 was released in September 1986 and was the first commercially available PC with the Intel 80386 Processor beating IBM to the punch. This document is a printed version of the early design specification.

Aug 22, 2014 · This processor is very interesting: It’s essentially a 386 core, updated to handle 486 instructions (there weren’t too many), and equipped with a whopping 16KB of write-back L1 cache. The 386-ness of the Blue Lightning is most apparent with regard to FPU architecture.
