	Intel 80486 - Wikipedia, the free encyclopedia
		The Intel i486 (also called 486 or 80486) is a range of 32-bit scalar Intel CISC microprocessors which is part of the Intel x86 family of processors.
		Intel 80486 OverDrive - i486SX, i486SX2, i486DX2 or i486DX4.
		Intel and IBM have broad cross-licenses of these patents, and AMD was granted rights to the relevant patents in the 1995 settlement of a lawsuit between the companies.

	Intel 486 (Site not responding. Last check: 2007-09-10)
		A range of Intel CISC microprocessors which is part of the Intel 80x86 family of processors.
		The main differences are that the 486 has an optimised instruction set, has an on-chip unified instruction and data cache, an optional on-chip floating-point unit (FPU), and an enhanced bus interface unit.
		The successor to the 486 is the Pentium.

	Intel 486 & 486 POD CPUID, S-spec, & Steppings
		Most Intel 486 CPUs with copyright dates of '92 or later (with the exception of the 486SL CPUs) support retrieving the CPUID at any point ("OTF", or "On-The-Fly") when the processor is operating.
		On a few Intel 486 processors with L1 cache that can be set to either Write-Through or Write-Back modes, the CPU will shift CPUIDs to show which mode the L1 cache is in at the time.
		The last Intel 486 core had only one stepping, "A", that denoted the CPU had either a 8 or 16Kb L1 cache that is settable to Write-Back mode (earlier 486 have an 8Kb L1 cache in Write-Through mode).

		The Intel 8088 was a version with an eight-bit external data bus.
		The Intel 8086 was based on the design of the Intel 8080 and Intel 8085 (it was source compatible with the 8080) with a similar register set, but was expanded to 16 bits.
		Intel bubble memory was on the market for a while, but faded away as better and cheaper memory technologies arrived.

		The 486 was the first to have an integrated floating point unit (FPU) to replace the normally separate math coprocessor (not all flavors of the 486 had this, though).
		The 486 chip was the first processor from Intel that was designed to be upgradeable.
		With the 486, the same CPU socket could accommodate several different flavors of the 486.

		Intel immediately responded with a federal copyright action alleging that AMD did not have a license to copy Intel's microcode (the "287 Microcode Litigation").
		AMD's Announcements Regarding Its Development of a "Clean Room" Version of its 486 Microprocessor In view of the uncertainty caused by the pending litigation, AMD concluded that it was prudent to develop a fully compatible version of Intel's 486 microprocessor that did not incorporate Intel's copyrighted 486 microcode.
		AMD's Disclosures Regarding the Clean Room 486 Microcode -- December 15, 1992 through June 4, 1993 On December 2, 1992, AMD moved for judgment notwithstanding the jury verdict in the 287 Microcode Litigation and a declaration that AMD's copyright license extended to future generations of Intel microcode.

	Upgrade Processors - Intel Overdrive CPU's
		Intel invariable introduced new form factors (sockets) leaving people with the old style to have no option but to replace that costly motherboard they had JUST bought.
		Intel's Overdrive series was based on a standard CPU, with additional voltage regulators, for example, a 3.3V 486 CPU would be built with regulators to work on the old style 5 Volt socket.
		Intels chips also included a heatsink, and later on a fan that was powered from the chip itself.

		Intel were first to market with it and sold the largest number; the AMD ones were very common too.
		The DX/2 was an exception: for the first time ever, Intel cut their prices to fight it out with AMD, and in consequence the Intel DX/2s were very popular and remained common on the market even after the cheaper AMD and Cyrix parts arrived.
		Intel never actually intended to manufacture a P-60, they were in fact 66MHz Pentiums that couldn't quite pass quality testing at their design speed.

	A CPU History
		Intel was not the only manufacturer playing in the sandbox at the time.
		While I am mentioning it here on the 486 page of the history lesson, it was actually AMD's competitive response to Intel's Pentium-class processor.
		Users of the Intel 486 processor, in order to get Pentium-class performance, had to make use of an expensive OverDrive processor or ditch their motherboard in favor of a true Pentium board.

		Intel's 486SX-20 was simply a cynical attempt to hoodwink buyers into spending quite a lot more on a chip that did quite a lot less.
		Essentially, a 486 is a very fast 32-bit 386DX CPU, and a 387 NPU, and 8k of cache RAM all on a single chip.
		The 486 bought a number of mainframe techniques into the X86 world for the first time: internal cache, rudimentary branch prediction, integrated NPU, and a five-stage pipeline.

		Like any large monolithic corporation, Intel proceeded to reap profits, and failed to invest in R&D. Demoralized, its chip designers left in droves to sell surfboards in the Carribean, joining those from other companies already left jobless by the destruction of the rest of the industry.
		Central Computers: While Intel sold the chips, IBM rebounded from its 20th century slump to be the computer system supplier of choice for Star Fleet.
		This was initially popularlized by Vulcan software peddlers who wanted to impress clients with their Intel association, but it soon became the greeting of choice in Vulcan society.

		With the market for the ubiquitous 386 now peaking and price erosion caused by the new 386 contenders setting in, Intel is busy trying to close off every conceivable thoroughfare to the 486 market with a saturation strategy that could leave little on the table in the next round.
		In its blocking effort to avoid a repeat performance, Intel is proliferating the 486 at both the high- and low-end, currently offering 10 different versions of the DX and SX, with dual-speed and highly integrated parts reportedly in the works.
		Intel recognized that they have to compete not only with AMD but with RISC, and they're responding very appropriately.
