Do You Recognize These? Early 8-Bit Microprocessors

Nov. 3, 2021

Back in the 70s and 80s, 8-bit microprocessors were the building blocks for early PCs and embedded systems.

This is part of the Do You Recognize This series in the Electronic History section of our Series Library.

We have come a long way since the Intel 8008 was released in April of 1972. The early 8-bit microprocessors sparked the personal-computer (PC) revolution and allowed embedded systems to be compact and inexpensive compared to the minicomputers and mainframes of that era.

I actually worked with most of these chips and can recognize them by the register sets. Can you?

This slideshow gallery presents the register sets of the major processor chips of this era. Each is followed by a short description of the processor.

We are interested in your suggestions as well as your feedback. Check out the rest of the Do You Recognize These series and take our 8-bit poll to see what others are doing with 8-bit micros.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
