What you can do in 5 minutes
- Write a tiny QuadBasic snippet and transpile it to Intel 4004 assembly.
- Build and run on a full MCS-4 lab setup with visible CPU and memory state.
- Adjust execution speed from instant run to slow inspection for learning.
New to the MCS‑4 angle? Read a short overview of the Intel 4004 emulator and MCS‑4 laboratory features for Windows.
Who this is not for
- Players looking for a casual arcade game
- Users expecting one-click modern app automation
- Anyone who does not want technical learning content
From QuadBasic to working 4004 code
- Write: start with a simple QuadBasic source.
- Transpile: generate Intel 4004 assembly output.
- Run: build, load ROM, and execute on the virtual lab.
