His Nibbler implements a 4-bit CPU using 7400 logic chips ... That’s a feat considering this is still just a design idea. It was made possible because he wrote a simulator based on the design.

Testing adapter design connects Arduino to the CPU boards Another interesting twist ... and he compares it with his 4-bit creation some in the build log. Thanks to [starhawk] for the tip.

The 4004 was the first commercially-produced microprocessor, or CPU. It was an enormous technical achievement for Intel, and the design team, which was led by Federico Faggin, broke new ground in ...

Yes, over half a century ago now, the Intel 4004 appeared in all its 4-bit glory (with its successor being the Intel 8080, later leading to the famous 8086 processor, ushering in the x86 era).

What was once considered a bad business venture, the 8008’s lasting legacy went on to drive the technological world we live in today. The history of Intel’s 8008 processor. Insight into the ...
