The Ultimate 4-Bit Engineering & Prototyping Laboratory

Quadium 4004 Workbench is a professional-grade simulation environment designed for computer historians, electronic engineers, and low-level programming enthusiasts. This is a "Solo Developer" project, built 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. Experience the inner workings of the first microprocessor with absolute visual clarity.

• QuadBasic Transpiler: Bridge the gap between eras. Program the 4004 using a high-level syntax that translates directly to native MCS-4 machine code, making 4-bit architecture accessible without losing technical depth.

• Hardware Patching & Peripherals: Configure your laboratory with a catalog of interactive modules. Connect virtual 7-segment displays (BCD/Mask), 8x8 LED, LCD, Pulse Gen, DIP-switches, and ASCII keyboards to simulate a complete physical workbench.

• Modern Export: Seamlessly integrate 1971 logic with 2026 workflows. Redirect emulated output directly to modern .txt files on your PC for data logging and external analysis.

Modular, Multi-Instance Workspace

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

• Floating Multi-Windows: Open multiple instances of RAM or ROM modules to monitor data flow across the entire system simultaneously.

• Custom Aesthetics: Switch instantly between high-visibility modern interfaces and nostalgic Retro-Amber or Phosphor-Green CRT aesthetics.

Comprehensive Learning Curriculum

Don't just emulate—understand. The Workbench includes an extensive library of integrated modules that guide you from basic logic gates to complex system interfacing. This collection is designed to grow, ensuring a deep grasp of early microprocessor architecture for both veterans and students.
