Processor History

*Processor History Details Pictures Only*
	1969: Four-Phase Systems AL1 The AL1 was an 8-bit bit slice chip containing eight registers and an ALUIt was designed by Lee Boysel in 1969 At the time, it formed part of a nine-chip, 24-bit CPU with three AL1s, but it was later called a microprocessor when, in response to 1990s litigation by Texas Instruments, a demonstration system was constructed where a single AL1 formed part of a courtroom demonstration computer system, together with RAM, ROM, and an input-output device
	1971: Pico/GI PICO1/GI250 In 1971 Pico Electronics and General Instrument (GI) introduced their first collaboration in ICs, a complete single chip calculator IC for the Monroe/Litton Royal Digital III calculator. This chip could also arguably lay claim to be one of the first microprocessors or microcontrollers having ROM, RAM and a RISC instruction set on-chip. The layout for the four layers of the PMOS process was hand drawn at x500 scale on mylar film, a significant task at the time given the complexity of the chip.
	1971: Intel 4004 The 4004 was Intel's first microprocessor. This breakthrough invention powered the Busicom calculator and paved the way for embedding intelligence in inanimate objects as well as the personal computer.
	1972: Intel 8008 The 8008 was twice as powerful as the 4004. A 1974 article in Radio Electronics referred to a device called the Mark-8 which used the 8008. The Mark-8 is known as one of the first computers for the home --one that by today's standards was difficult to build, maintain and operate.
	1974: Intel 8080 The 8080 became the brains of the first personal computer--the Altair, allegedly named for a destination of the Starship Enterprise from the Star Trek television show. Computer hobbyists could purchase a kit for the Altair for $395. Within months, it sold tens of thousands, creating the first PC back orders in history.
	1974: Texas Instruments TMS1000
	1974: National Semiconductor "Pace" 16Bit
	1975: Motorola 6502
	1976: Zilog Z80
	1978: Intel 8086-8088 A pivotal sale to IBM's new personal computer division made the 8088 the brains of IBM's new hit product--the IBM PC. The 8088's success propelled Intel into the ranks of the Fortune 500, and Fortune magazine named the company one of the "Business Triumphs of the Seventies."
	1979: Motorola 68000
	1981: HP 32 bit
	1982: Intel 80286 The 80286, originally known as the 80286, was the first Intel processor that could run all the software written for its predecessor. This software compatibility remains a hallmark of Intel's family of microprocessors. Within 6 years of its release, an estimated 15 million 80286-based personal computers were installed around the world.
	1985: Intel 80386 The Intel386™ microprocessor featured 275,000 transistors--more than 100times as many as the original 4004. It was a 32-bit chip and was "multi tasking," meaning it could run multiple programs at the same time.
	1989: Intel 80486 The 80486 processor generation really meant you go from a command-level computer into point-and-click computing. "I could have a color computer for the first time and do desktop publishing at a significant speed," recalls technology historian David K. Allison of the Smithsonian's National Museum of American History. The 80486 processor was the first to offer a built-in math coprocessor, which speeds up computing because it offloads complex math functions from the central processor.
	1989: AMD486DX
	1993: Intel Pentium The Pentium processor allowed computers to more easily incorporate "real world" data such as speech, sound, handwriting and photographic images. The Intel Pentium brand, mentioned in the comics and on television talk shows, became a household word soon after introduction.
	1995: Intel Pentium Pro Released in the fall of 1995 the Pentium Pro processor is designed to fuel 32-bit server and workstation applications, enabling fast computer-aided design, mechanical engineering and scientific computation. Each Pentium Pro processor is packaged together with a second speed-enhancing cache memory chip. The powerful Pentium Pro processor boasts 5.5 million transistors.
	1997: Intel Pentium II The 7.5 million-transistor Pentium II processor incorporates Intel MMX™ technology, which is designed specifically to process video, audio and graphics data efficiently. It was introduced in innovative Single Edge Contact (S.E.C) Cartridge that also incorporated a high-speed cache memory chip. With this chip, PC users can capture, edit and share digital photos with friends and family via the Internet; edit and add text, music or between-scene transitions to home movies; and, with a video phone, send video over standard phone lines and the Internet.
	1998: Intel Pentium II Xeon The Pentium II Xeon processors are designed to meet the performance requirements of mid-range and higher servers and workstations. Consistent with Intel's strategy to deliver unique processor products targeted for specific markets segments, the Intel® Pentium II Xeon processors feature technical innovations specifically designed for workstations and servers that utilize demanding business applications such as Internet services, corporate data warehousing, digital content creation, and electronic and mechanical design automation. Systems based on the processor can be configured to scale to four or eight processors and beyond.
	1999: Intel Celeron Continuing Intel's strategy of developing processors for specific market segments, the Celeron processor is designed for the value PC market segment. It provides consumers great performance at an exceptional price, and it delivers excellent performance for uses such as gaming and educational software.
	1999: Intel Pentium III The Pentium III processor features 70 new instructions--Internet Streaming SIMD extensions-- that dramatically enhance the performance of advanced imaging, 3-D, streaming audio, video and speech recognition applications. It was designed to significantly enhance Internet experiences, allowing users to do such things as browse through realistic online museums and stores and download high-quality video. The processor incorporates 9.5 million transistors, and was introduced using 0.25-micron technology.
	1999: Intel Pentium III Xeon™ The Pentium III Xeon processor extends Intel's offerings to the workstation and server market segments, providing additional performance for e-Commerce applications and advanced business computing. The processors incorporate the Pentium III processor's 70 SIMD instructions, which enhance multimedia and streaming video applications. The Pentium III Xeon processor's advance cache technology speeds information from the system bus to the processor, significantly boosting performance. It is designed for systems with multiprocessor configurations.
	2000: Intel Pentium 4 Users of Pentium 4 processor-based PCs can create professional-quality movies; deliver TV-like video via the Internet; communicate with real-time video and voice; render 3D graphics in real time; quickly encode music for MP3 players; and simultaneously run several multimedia applications while connected to the Internet. The processor debuted with 42 million transistors and circuit lines of 0.18 microns. Intel's first microprocessor, the 4004, ran at 108 kilohertz (108,000 hertz), compared to the Intel® Pentium® 4 processor's initial speed of 1.5 gigahertz (1.5 billion hertz). If automobile speed had increased similarly over the same period, you could now drive from San Francisco to New York in about 13 seconds.
	2001: Intel Xeon The Xeon processor is targeted for high-performance and mid-range, dual-processor workstations, dual and multi-processor server configurations coming in the future. The platform offers customers a choice of operating systems and applications, along with high performance at affordable prices.
