* In 1982, Burroughs began producing personal computers, the B20 and B25 lines with the Intel 8086 / 8088 family of 8-bit chips as the processor.

The Intel 4004 was a 4-bit processor released in 1971, but in 1973 the Intel 8080, an 8-bit processor, made the first personal computer, the Altair 8800, possible.

Industry Standard Architecture ( ISA ) is a computer bus standard for IBM PC compatible computers introduced with the IBM Personal Computer to support its Intel 8088 microprocessor's 8-bit external data bus and extended to 16 bits for the IBM Personal Computer / AT's Intel 80286 processor.

IBM designed the 8-bit version as a buffered interface to the external bus of the Intel 8088 ( 16 / 8 bit ) CPU used in the original IBM PC and PC / XT, and the 16-bit version as an upgrade for the external bus of the Intel 80286 CPU used in the IBM AT.

The Intel 8080 was the second 8-bit microprocessor designed and manufactured by Intel and was released in April 1974.

The Intel 8088, released in 1979, was a slightly modified chip with an external 8-bit data bus ( allowing the use of cheaper and fewer supporting logic chips ), and is notable as the processor used in the original IBM PC.

In 1972, Intel launched the 8008, the first 8-bit microprocessor .< ref > using enhancement load PMOS logic ( demanding 14V, achieving TTL-compatibility by having V < sub > CC </ sub > at + 5V and V < sub > DD </ sub > at-9V )</ ref > It implemented an instruction set designed by Datapoint corporation with programmable CRT terminals in mind, that also proved to be fairly general purpose.

The Intel 80C88. The 8088 was targeted at economical systems by allowing the use of an 8-bit data path and 8-bit support and peripheral chips ; complex circuit boards were still fairly cumbersome and expensive when it was released.

The first widely adopted 8-bit microprocessor was the Intel 8080, being used in many hobbyist computers of the late 1970s and early 1980s, often running the CP / M operating system ; it had 8-bit data words and 16-bit addresses.

The first commercial 8-bit processor was the Intel 8008 ( 1972 ) which was originally intended for the Datapoint 2200 intelligent terminal.

Most competitors to Intel started off with such character oriented 8-bit microprocessors.

A representative system of this era would have used an S100 bus, an 8-bit processor such as a Intel 8080 or Zilog Z80, and either CP / M or MP / M operating system.

In 1972, for the first time is marketed a solid state computer designed with a microprocessor ( the Intel 8008 8-bit microprocessor ).

Featuring 8-bit processors, typically the MOS Technology 6502, Intel 8080 or the Zilog Z-80, along with rudimentary input and output interfaces and as much RAM as practical, these systems started out as kit-based hobbyist computers but soon evolved into an essential business tool.

The Intel 8748 has on-chip clock oscillator, 2 8-bit timers, 27 I / O ports, 64 bytes of RAM and 1 KB of EPROM.

Zilog, Inc., previously known as ZiLOG ( which stands for " Z ( the last word of ) integrated logic "), is an American manufacturer of 8-bit and 16-bit microcontrollers, and is most famous for its Intel 8080-compatible Z80 series.

The Z80 ( i ) was an improved implementation of the Intel 8080 architecture, which was faster, more capable, and much cheaper ; alongside the 6502 it was one of the most popular 8-bit processors for general purpose microcomputers and other applications.

Although the 8080 was generally an 8-bit processor, it also had limited abilities to perform 16-bit operations: Any of the three 16-bit register pairs ( BC, DE, HL ) or SP could be loaded with an immediate 16-bit value ( using LXI ), incremented or decremented ( using INX and DCX ), or added to HL ( using DAD ).

The 8086 was introduced during 1978 as a fully 16-bit extension of Intel's 8-bit based 8080 microprocessor and also introduced memory segmentation to overcome the 16-bit addressing barrier of such designs.

The Z80 took over from the 8080 and its offspring, the 8085, in the processor market, and became one of the most popular 8-bit CPUs.

Like on the 8080, 8-bit registers are typically coupled to provide 16-bit versions.

Digital Research's original CP / M for the 8-bit Intel 8080 and Z-80 based systems spawned numerous spin-off versions, most notably CP / M-86 for the Intel 8086 / 8088 family of processors.

Unlike the 8080 it does not multiplex state signals onto the data bus, but the 8-bit data bus was instead multiplexed with the lower part of the 16-bit address bus to limit the number of pins to 40.

It met IBM's main criteria: it looked like CP / M, and it was easy to adapt existing 8-bit CP / M programs to run under it, notably thanks to the TRANS command which would translate source files from 8080 to 8086 machine instructions.

These 16-bit CPUs were an evolution of the previous generation of 8-bit CPUs such as the 8080, inheriting many characteristics and instructions, extended for the 16-bit era.

* The Intel 8080 microprocessor ( 1974 ) was the first high-performance 8-bit microprocessor, using the faster n-channel silicon gate technology.

Intel's 432 project started in 1975, a year after the 8-bit Intel 8080 was completed and a year before their 16-bit 8086 project began.

These were designed for use with 8080 or similar processors and used an 8-bit data bus.

Doerr joined Intel Corporation in 1974 just as the firm was developing the 8080 8-bit microprocessor.

The chips primarily competed against Intel's 8-bit family of chips ( such as the 8080, or their relations, the ZiLOG Z80 range ).

* MIDAS ( operating system ) ( Microsoft Interrupt Driven Asynchronous System ), an 8-bit operating system for 8080 / Z80 in 1980, originally developed as MDOS by Microsoft's Marc McDonald in 1979

CISC does not even need to have complex addressing modes ; 32 or 64-bit RISC processors may well have more complex addressing modes than small 8-bit CISC processors.

Reading Atari 8-bit 130kB or 180kB disks was possible as well with special software, but the standard Atari 8-bit 90kB format, which used FM rather than MFM encoding, could not be handled by the 1571 hardware without modifying the drive circuitry as the control line that determines if FM or MFM encoding is used by the disc controller chip was permanently wired to ground ( MFM mode ) rather than being under software control.

Other well known 8-bit microprocessors that emerged during these years were Motorola 6800 ( 1974 ), General Instrument PIC16X ( 1975 ), MOS Technology 6502 ( 1975 ), Zilog Z80 ( 1976 ), and Motorola 6809 ( 1978 ).

This meant that in spite of its modest 8-bit CPU the system compared well against the 16-bit machines in the market at the time.

Furthermore, fuzzy logic is well suited to low-cost implementations based on cheap sensors, low-resolution analog-to-digital converters, and 4-bit or 8-bit one-chip microcontroller chips.

Even some consumer products were given light pens, such as the Thomson MO5 computer family as well as the Atari 8-bit home computers.

Another reason is that the hardware they evolved on initially shipped with minimal amounts of computer memory — 4-8 kilobytes was standard on early home computers — as well as 8-bit processors without specialized support circuitry like a MMU or even a dedicated real-time clock.

On February 19, 2009, Zilog announced that it had sold off their 8-bit Crimzon Universal Remote Control infrared microcontroller product line, as well as their ARM9 32-bit microcontrollers, including the Zatara security microcontrollers and 15 patents, to Maxim Integrated Products.

Millipede was ported to Atari's 8-bit and ST computer line as well as the Atari 2600.

Bloodwych is a dungeon role-playing video game developed for the Amiga, Atari ST and MS-DOS as well as the major 8-bit home computer platforms.

In the Windows NT-based versions of Windows, Notepad can edit traditional 8-bit text files as well as Unicode text files ( both UTF-8 and UTF-16, and in case of UTF-16, both little-endian and big-endian ).

Multiprogramming, memory protection, generalized interrupts, the 8-bit byte were all concepts later incorporated in the IBM System / 360 line of computers as well as most later CPUs.

While having a limited total number of colors in an image is somewhat restrictive, nevertheless they can be well chosen, and this scheme is markedly superior to 8-bit color.

It is a version of the Motorola 68000 with an 8-bit external data bus, as well as a smaller address bus.

The method allows for an unprecedented four ( software-mixed ) channels of 8-bit samples with optional filtering on top of all samples, as well as two ordinary SID sound channels.

The games in the Alternate Reality series were developed on the Atari 8-bit family of home computers, but were ported to other platforms as well.

The 8-bit AppleWorks is sometimes referred to as " AppleWorks Classic " in order to differentiate it from AppleWorks GS as well as the later product for Macintosh and Windows of the same name.

The KoalaPad is a graphics tablet produced from 1984 by U. S. company Koala Technologies for several early 8-bit home computers, including the Apple II family, TRS-80 Color Computer ( TRS-80 Touch Pad ), Atari 8-bit family, and Commodore 64, as well as for the IBM PC.

The Commodore 8-bit machines ' KERNAL consisted of the low-level, close-to-the-hardware OS routines roughly equivalent to the BIOS in IBM PC compatibles ( in contrast to the BASIC interpreter routines, also located in ROM ) as well as higher-level, device-independent I / O functionality, and was user-callable via a jump table whose central ( oldest ) part, for reasons of backwards compatibility, remained largely identical throughout the whole 8-bit series.

( Oasis 8-bit was quite well optimised by that point, with many parts hand-coded in Z80 assembler, which meant that most early then-new 16-bit systems performed nowhere near as well as their 8-bit counterparts ).
