TL;DR
A computer enthusiast has assembled a complete 6502 microprocessor-based system from scratch, connecting it to a vintage Minitel terminal for user interface. This project demonstrates retro computing capabilities and DIY hardware skills.
A hobbyist has successfully built a fully operational 6502 microprocessor-based computer from scratch and connected it to a Minitel terminal for display and input. This project highlights the capabilities of vintage hardware and DIY electronics, and it demonstrates a practical use of obsolete technology in modern hobbyist contexts.
The creator, known online as ‘Memo-1’, assembled the 6502 CPU from individual components, designing and soldering the circuit board without using pre-made kits. The system is capable of running simple programs, with the Minitel serving as the terminal interface, providing a text-based display and keyboard input.
According to Memo-1, the project took several months of work, involving both hardware assembly and software development. The Minitel, a French videotex terminal from the 1980s, was repurposed as a display device, connecting via serial interface to the custom-built motherboard. The setup is fully functional, allowing basic computing tasks to be performed through the vintage terminal.
Why Rebuilding Vintage Hardware Matters Today
This project underscores the enduring relevance of early microprocessor technology and demonstrates how vintage hardware can be repurposed for modern DIY projects. It also highlights the skills involved in hardware assembly, programming, and interfacing older devices with contemporary or custom-built systems, inspiring hobbyists and educators alike.
Additionally, the use of a Minitel as a terminal illustrates how obsolete technology can find new life in educational or experimental contexts, fostering appreciation for early computer interfaces and encouraging preservation of vintage tech skills.

Retro Computing and DIY Hardware Revival
The 6502 microprocessor, introduced in 1975, powered early personal computers such as the Apple I and Commodore 64. Over the decades, enthusiasts have recreated or emulated 6502 systems for educational and hobbyist purposes. The Minitel, a French videotex terminal introduced in the early 1980s, was widely used for online services before internet access became prevalent.
Recent years have seen a surge in DIY hardware projects, with hobbyists building computers from scratch, often using vintage components or designing custom circuits. Memo-1’s project fits into this trend, combining a classic CPU with a vintage terminal interface to create a tangible, functional retro computer system.
“Building this 6502 computer was a challenging but rewarding experience. Connecting it to a Minitel gave it a unique vintage interface that’s both nostalgic and functional.”
