| | CPU-World: Intel 8080 family |
 | | Intel 8080 microprocessor is a successor to the Intel 8008 CPU. | | | To ease transition to the 8080 Intel made the new microprocessor source code compatible with the 8008. | | | Interrupt processing logic didn't change from the 8008, which also helped to port old software to the 8080 processor. |

| | Intel Preface to 8085 CPU |
| | Consider an 8080 microcomputer used within an automatic computing scale for a supermarket. | | | In fact, the 8080 instruction set is powerful enough to rival the performance of many of the much higher priced minicomputers, yet the 8080 is upward software compatible with Intel's earlier 8008 microprocessor (i.e., programs written for the 8008 can be assembled and executed on the 8080). | | | The 8080, with instruction times as short as 2 1lsec., is an order of magnitude faster than earlier generations of microcomputers, and therefore has an expanded field of potential applications. |

| | Kildall's task at Intel that year was to design and develop a language called PL/M for the 8080 chip, to be used as a systems development language. | | | Intel was so busy selling bucketloads of 8080 chips to the many small and growing computer manufacturers that it didn't miss a dubious opportunity to get into the software business one bit. | | | The plan was for Gary to use the 8080 emulator Intel had running on their big PDP-10 minicomputer, but he preferred to work directly on the 8080 itself, in part because by working on his own machine at home he could avoid the 50 mile drive to Intel to work every day. |

| | Unit One A Brief History of Microprocessors Microcontrollers |
| | Intel have gone on to develop a range of other microcontrollers that are more complex than the basic original devices (see http://developer.intel.com for more details). | | | In the case of the Intel range of microprocessors, the 8080 evolved into the 8085 (also 8 bit like the 8080), then the third generation 16 bit 8086 microprocessor which, in its 8088 pseudo 16 bit form, was used in the first IBM PCs. | | | In due course the Intel 8080 core processor was used for a range of microcontrollers (8048 and 8051 to name but two). |

| | Intel Celebrates The Industry's 1 Billionth PC |
| | Intel's contribution to the evolution of personal computing began with its 1971 invention of the microprocessor, often referred to as the brain of the PC. | | | From the Intel 8080 chip used in the Altair to the 4.77 MHz Intel® 8088 processor that powered the watershed IBM PC in 1981, this historic path of innovation has brought us today to the era of the Intel® Pentium® 4 processor, the world's fastest processor. | | | Intel believes that as technology goes increasingly global, the focus must remain on developing the faster, more powerful processor technologies that users covet, while enabling "anytime, anywhere" computing and making PCs more intuitive and easier to use. |

| | Intel put itself back on the map with the 8080, which used the same instruction set as the earlier 8008 and is generally considered to be the first truly usable microprocessor. | | | Lesser-known Intels from this time include the nearly forgotten 4040, which added logical and compare instructions to the 4004, and the ill-fated 32-bit Intel 432. | | | These were the first Intel chips to be produced without input from Faggin. |

| | Instead, Intel officials suggested that the calculator be built around a single general-purpose computing chip, which eventually became known as the 4004. | | | After the 8080 appeared, Gary Kildall of Digital Research saw the potential for low-cost computing devices and created an operating system called CP/M. This software simplified basic user ta sks such as creating, executing, and debugging programs. | | | In 1978, Intel developed two sibling devices, the 8088 and the 8086, as upgrades to the popular 8080. |
