Quadium 4004 Workbench

The 4-Bit Engineering and Prototyping Laboratory (NOTICE: Engineering software, not a game)

Quadium 4004 Workbench is a professional-grade simulation environment designed for computer historians, electronics engineers, and low-level programming enthusiasts. It is a solo developer project, created with the rigor and passion of a senior engineer to preserve and explore the MCS-4 ecosystem (CPU, RAM, ROM, and I/O) exactly as it was conceived in 1971.

Key Features for the Modern Engineer

• Transparent logic: No "black boxes." Monitor every register, bus, and memory cell in real time with complete visual clarity.

• QuadBasic Transpiler: Bridge the generational gap. Program the 4004 using a high-level syntax that translates directly into native MCS-4 machine code.

• Hardware Patching and peripherals: Connect 7-segment displays, LED matrices, LCDs, DIP switches, or link your workbench to physical microcontrollers (Arduino) via the USB I/O Bridge.

• Modern export capabilities: Seamlessly integrate 1971 logic into today's workflows. Redirect emulated data directly to .txt files for external analysis.

Multi-Instance Modular Workspace

Designed for serious experimentation, the Workbench provides a fully flexible interface:

• Multiple floating windows: Open multiple instances of RAM or ROM modules to monitor data flow across the entire system simultaneously.

• Customizable appearance: Instantly switch between modern high-visibility interfaces and nostalgic CRT-inspired themes in Retro-Amber or Phosphor-Green.

Comprehensive Learning Path

Go beyond emulation—develop a deep understanding. The Workbench includes an extensive library of integrated modules that guide you from basic logic gates to complex system interfacing. A collection designed to grow over time, ensuring a thorough understanding of early microprocessor architecture for both seasoned professionals and students alike.
