DIY Enthusiast Crafts Fully Functional CPU from Vintage Memory Chips

07/19/2025

In an extraordinary feat of engineering and retro-computing passion, a Polish individual operating under the alias MINT has meticulously assembled a fully operational central processing unit using only antique memory modules. This remarkable endeavor underscores the foundational mechanics of computing and showcases how a deep understanding of hardware can transform seemingly obsolete components into a functional system. The project, spanning a period of three months, involved intricate hand-soldering of numerous wires and writing thousands of lines of assembly code, drawing inspiration from classic 8-bit microprocessors of computing's nascent era.

MINT embarked on this ambitious undertaking after accumulating a substantial collection of aged memory chips. Initially, these components served as the basis for simpler circuits, such as controlling lights or motors. However, the vision soon expanded to explore the possibility of creating a complete 8-bit CPU from these salvaged parts. The culmination of this dedicated effort is the “EPROMINT CPU,” a device capable of executing commands and even rendering basic visuals. As a compelling demonstration of its capabilities, the bespoke processor was configured to play pixelated sequences from the iconic film “The Matrix” on a Vacuum Fluorescent Display (VFD), proving the viability of this unique, self-made computing unit.

This inspiring project demonstrates that groundbreaking technological achievements are not solely dependent on vast resources or large teams. Instead, it highlights the power of individual curiosity, perseverance, and a hands-on approach to understanding complex systems. MINT's creation serves as a testament to the accessible nature of fundamental computer science, illustrating that with enough dedication, anyone can delve into the core principles of how computers function and even build their own from the ground up.
