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.
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
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
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
Go beyond simulation by communicating with Arduino-compatible devices over USB, allowing programs running on the Intel 4004 to interact with real electronics.
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
Integrated documentation
Perfect for students, programmers, makers, electronics enthusiasts, retrocomputing fans and anyone interested in computer architecture or low-level programming.
No previous knowledge of the Intel 4004 is required.
Quadium doesn't just emulate the Intel 4004, it helps you understand it.
Follow every instruction, inspect every register, observe every hardware interaction and discover how the microprocessor that started the personal computing revolution really worked.
Thank you First of all, thank you for the warm welcome. The reception this demo is getting still catches me off guard, in the best way. What’s in this update Follow PC — fixed for pause + step when a high clock speed is selected. Campaign — Notebook 00 is playable in the demo. Russian — translation is now available as work in progress (WIP). If something feels off, please tell me. I read every report. Thank you again for being here. — Jaime
