From the project
Modular 8-bit computer built with TTL logic units to create a "Simple as Possible" system
This project showcases the design and construction of a modular 8-bit computer built with TTL logic units. The core principle behind the project is to create a "Simple as Possible" system, focusing on simplicity, modularity, and compactness.
- TTL Logic-Based Design: The computer is built using traditional TTL (Transistor-Transistor Logic) components, adhering to a fundamental, hands-on approach to computing. - Modular Architecture: Designed for modularity, each functional unit (ALU, registers, memory, control logic, etc.) is implemented as a separate module, allowing for easy debugging…
