Happy birthday x86!

Thirty years ago Intel released the first x86 processor - the 8086. Happy birthday x86!
Thirty years ago, on June 8, 1978, Intel Corp. introduced its first 16-bit microprocessor, the 8086, with a splashy ad heralding "the dawn of a new era." Overblown? Sure, but also prophetic. While the 8086 was slow to take off, its underlying architecture -- later referred to as x86 -- would become one of technology's most impressive success stories.

"X86" refers to the set of machine language instructions that certain microprocessors from Intel and a few other companies execute. It essentially defines the vocabulary and usage rules for the chip. X86 processors -- from the 8086 through the 80186, 80286, 80386, 80486 and various Pentium models, right down to today's multicore chips and processors for mobile applications -- have over time incorporated a growing x86 instruction set, but each has offered backward compatibility with earlier members of the family.

In the three decades since the introduction of the 8086, the x86 family has systematically progressed from desktop PCs to servers to portable computers to supercomputers. Along the way, it has killed or held at bay a host of competing architectures and chip makers. Even some markets that had seemed locked up by competitors, such as Apple's use of Motorola PowerPCs in the Macintosh computer, have yielded to x86 in recent years.

It's definitely been a fun ride :) Back when a tube full of chips would increase your memory from 256k to 512k...
