Quadium 4004 Workbench

Program the Microprocessor That Started It All

Learn how a real microprocessor works by programming, debugging and experimenting with the Intel 4004, the world's first commercial microprocessor.

Quadium 4004 Workbench combines a complete development environment with an integrated learning platform, allowing you to write software, inspect microprocessor execution in real time, interact with virtual hardware and even communicate with real devices through USB.

Designed for learning, experimentation and development. Quadium is educational engineering software, not a traditional game.

Program

Create your own Intel 4004 software using an integrated multi-window workbench.

• Intel 4004 Assembly

• QuadBasic (translated into native Intel 4004 machine code)

• Integrated editor

• Configurable workspace

Debug

Observe exactly what happens inside the microprocessor as your code executes.

• Step-by-step execution

• Breakpoints

• Live registers

• RAM and ROM inspection

• Stack viewer

• Execution trace

Experiment

Watch software interact with hardware in real time through a collection of virtual peripherals.

• LEDs

• Seven-segment displays

• LCD displays

• LED matrix

• Keyboard and switches

• Printer

• Square-wave generator

• Memory devices

Connect Real Hardware

Go beyond simulation by communicating with Arduino-compatible devices over USB, allowing programs running on the Intel 4004 to interact with real electronics.

Learn

Whether you're discovering assembly language for the first time or exploring one of the most influential microprocessors ever created, Quadium includes everything you need to learn at your own pace.

• Interactive lessons

• Guided Labs

• Programming examples

• Opcode reference

• Tips & snippets
