I've wanted to make ix86 computer from parts for long time and when I encounter 8086, I always got it if the price is not so high..As in above picture, I got 8086s (and 8087) by bon-marché but 8086 is not micro-controller but real CPU which can...
The Weird CPU (TTA8) Here is my 8 bit Weird CPU (https://hackaday.io/project/12879-weird-cpu) in action (playing LED Light Chaser): When programming, the bottom (red) LEDs are for the memory address entry, and the top (yellow) are for data entry....
What kind of CPU can you describe in one page of code? Will it be usable? (You bet! In fact we've found it to be a pleasure to program.)Having previously built a short series of one-page 8 bit CPUs for CPLD, we wanted more space, and decided to target...
The idea for this design was born at the end of januari (2023). While many homebuilt CPU's have their own, unique instruction set, I decided that for this project the CPU would use an existing instruction set. Also, I wanted to build the computer...

Concept My last PC was very noisy and old so I had the dream to build a complete passive PC. After some search I thought that it schould be possible. Follow the logs to see how I finally succeeded. Let's start with some interessting links I found in...
MKHBC-8-R2 - Multipurpose 8-bit Homebrew Microcomputer. Design and Specifications. 1. Architecture of the system. The system is intended as a hobbyist computing/microcontroller expandable platform. The CPU of choice is MOS 6502 compatible microprocessor....
History followed one pathThere were many other waysIt will always be like that Can fewer than 40 old-skool TTL chips implement a multi-megahertz microcomputer with video and sound? This project started as an exploration of what you can build from 30-40...
Counting the GPIOs... With the intention of using the Raspberry Pico micro controller, I needed to understand how many GPIOs would be required to carry all of the necessary signals: 16 X Address Lines8 X Data LinesMREQ signalWR signalRD signal....
Having completed building my version of Ben Eater's 8-bit breadboard computer nearly a year ago, building my own Apple 1 clone, building and looking into the inner workings of the Gigatron kit and studying the book Digital Computer Electronics it...
Introduction I wanted to see how far I could push the Cortex M0+ of the Arduino Zero. I think it is a balanced microcontroller: not too limited like an AVR, not too fancy, like a Cortex M4 (which has enough computing power even to run Doom). I wanted...
IntroductionI'm an Electronics Engineer. I began to explore the world of electronics during my 3rd year at Novosibirsk State University. In addition, at that time Arduino (based on AVR chips) was growing in popularity. However, Arduino wasn’t interesting...
