Examples of Intel 8008

The Intel 8008 microprocessor, introduced in 1972, played a significant role in various technological advancements of the time. Here are three real-world examples of its applications:

Datapoint 2200 Terminal: Developed by the Computer Terminal Corporation (later known as Datapoint Corporation), the Datapoint 2200 was an early programmable terminal that used Intel’s 8008 microprocessor. It was essentially an all-in-one computer and was considered a predecessor to personal computers. Datapoint 2200 Terminal allowed users to connect to mainframe computers and perform various tasks, including data entry and storage.

CTC’s Advanced Communications Controller (ACC): The Intel 8008 microprocessor was also utilized in an early Advanced Communications Controller developed by CTC. The controller facilitated communication between the Datapoint 2200 Terminal and large mainframe systems. This helped in handling multiple user terminals and centralizing computing resources.

Heathkit H8: Launched in 1977, the Heathkit H8 was an early personal computer kit based on the 8008 microprocessor. It was one of the first consumer products that featured a CPU from the Intel 8000 series, which paved the way for more advanced and powerful personal computers. The H8 provided users with various computing capabilities, including BASIC programming and a command line interface for operation.

Intel 8008 FAQ

What is the Intel 8008?

The Intel 8008 is an early microprocessor, designed by Intel and released in 1972. It was the first 8-bit microprocessor and the basis for the later, more popular Intel 8080 and 8085 processors. The 8008 was limited by its 14-bit address space, but it initiated the evolution of the modern personal computer.

What is the history of the Intel 8008?

The Intel 8008 was initially designed for the Datapoint 2200 programmable terminal. However, due to various delays in its production, Datapoint decided to go with another processor. Intel later decided to release the 8008 as a stand-alone product, making it the first general-purpose microprocessor in the market.

What are the main features of the Intel 8008?

The Intel 8008 has an 8-bit architecture and a 14-bit address bus, allowing it to address up to 16 KB of memory. It had 74 instructions and seven 8-bit registers. The 8008’s clock speed ranged from 500 kHz to 800 kHz, and its design was based on PMOS technology.

What was the Intel 8008 used for?

The Intel 8008 was used in various early computer systems, such as the Mark-8 and Micral-N, which were some of the first microcomputer systems. It was also used in industrial control systems, early point-of-sale terminals, and various hobbyist projects. Although it had limitations compared to later processors, it set the stage for the development of modern personal computing.

How did the Intel 8008 evolve into the Intel 8080?

Intel built upon the experience from the 8008 and designed the Intel 8080, which was released in 1974. The 8080 addressed the limitations of the 8008 by providing a 16-bit address bus, an extended instruction set, a more efficient implementation of registers, and a faster clock speed. The Intel 8080 quickly gained popularity and became the foundation for several early personal computers, such as the MITS Altair 8800 and the IMSAI 8080.
