[Scott Baker] is at it again and this time he has built a 4-bit single board computer based on the Intel 4004 microprocessor. In the board design [Scott] covers the CPU (both the Intel 4004 and 4040 ...

Dan Geiger has created a new learning platform which has been specifically designed to teach you how a computer works at the most fundamental level, and even allows you to program in machine language ...

What we are going to do is design a simple 4-bit computer at the primitive logic gate and flip-flop level and then implement it in the technology of our choice I’ve often wondered what would happen if ...

New research paper titled “FlexiCores: low footprint, high yield, field reprogrammable flexible microprocessors” from researchers at University of Illinois and PragmatIC Semiconductor. “Flexible ...

Hardware hacker Dmitry Grinberg recently achieved what might sound impossible: booting Linux on the Intel 4004, the world’s first commercial microprocessor. With just 2,300 transistors and an original ...

[Michael Gardi] wrote in to let us know about his project: CPS-1: Imagining An Early 70s 4-bit Microcomputer. The CPS-1 was the first Canadian microprocessor-based computer. It was built by ...

People talking about booting things on Turing machines might enjoy this recent one from Ken Shirriff on the Minuteman III missile's guidance system. It has NO RAM and uses serial processing, reading ...

The term "Bit Slicing" was once dominant in history books as a technique for constructing a processor from processor modules of smaller bit width where each of these components processes one field or ...
