“A custom pc based on 8085 with custom assembler and EEPROM programmer. This project consist of an assembler project written in Python in order to translate the assembly code into machine code recognizable from the 8085 microprocessor, acustom EEPROM writer …
“Vectron VGA Plus Text Mode simplifies displaying text with retro computers and microcontrollers by hiding the pixel-level details. Supply only row and column positions, and an ASCII character code, to write text to a 40x30 character VGA display. How It …
“Vectron VGA Plus is a VGA graphics adapter that can interface with retro computers or microcontrollers. How It Works I previously built a massive 7400-logic based VGA generator called Vectron VGA. While it was a nice project to build, it …
“After various experiments and failed attempts to design a 7400-based computer, I came to a quite minimalistic 8-bit approach which is nevertheless pretty versatile and can utilize a surprisingly large amount of memory resources. The CPU core itself executes its …
“32 bit RISC-V homemade In this article I will describe how I designed and made a functional 32 bit RISC-V CPU at home. Specifications: “Max” clock speed: 500 kHz Program memory: 512 kB RAM size: 512 kB VGA …
“This project is 7400 series logic ICs based clock. It keeps time solely based on discrete logic ICs and a stable clock source. For the display LEDs, I am using common anode 7 segment displays. This variant is 0.56 …
“The MK1 CPU is composed of several modules, all connected trough a common 8-bit BUS, the status of each module is shown by dedicated LEDs. The clock module is designed to allow step-by-step execution; in automatic mode the clock speed …
“Vectron Handheld is a retro handheld gaming console based on the 6502 CPU. It has five input buttons (up, down, left, right, fire) and a 1.8” 128x160 18-bit color TFT LCD display. I have developed an implementation of Pong …
“A microprocessor built with TTL chips. In one square inch. What would be cool for the square inch contest or Hackaday prize…. How about a homebrew CPU with TTL chips ? This is the smallest TTL Homebrew CPU in the world …
“This project demonstrates the basics of digital logic, the characteristics of a NE555 timer, and demonstrates how binary numbers are counted. The components used are: a NE555 timer, a 12-bit ripple counter, two 2-input NOR gates, a 4-input AND gate …
