TL;DR
A programmer has developed a BASIC interpreter capable of booting on UEFI machines. This project demonstrates a modern take on classic programming environments, with potential educational and hobbyist applications.
A developer has created a BASIC interpreter that boots directly on UEFI systems, a feat that combines modern firmware standards with vintage programming environments. This project allows users to run a classic BASIC interpreter without the need for an operating system, directly from UEFI firmware, which is the modern replacement for BIOS. The developer, who posted the project on Show HN, aims to demonstrate the feasibility of running simple, retro-style programming environments at the firmware level, opening possibilities for hobbyists, educators, and system programmers.
The project involves writing a minimal BASIC interpreter that can initialize during the UEFI boot process. Unlike traditional interpreters that run within an OS, this implementation is embedded directly into the firmware, allowing it to launch immediately when the machine powers on. The developer reported that the interpreter supports line numbers, immediate mode, simple graphics, strings, and arrays, mimicking vintage BASIC environments. The code is publicly available, and the developer has provided instructions for flashing the firmware with the custom UEFI application.
This achievement was made possible by leveraging UEFI’s ability to run custom applications during the boot process. The developer emphasized that the interpreter is lightweight and designed to demonstrate the technical possibility rather than replace modern operating systems. The project was motivated by a desire to explore retro computing in a modern context, combining the simplicity of old-school BASIC with the flexibility of UEFI firmware.
Implications for Retro Computing and Firmware Development
This development demonstrates that it is technically feasible to embed simple programming environments directly into UEFI firmware, bypassing traditional operating systems. It opens pathways for creating lightweight, self-contained programming tools that can run at the firmware level, which could be useful for educational purposes, system diagnostics, or hobbyist experimentation. The project also highlights the flexibility of UEFI as a platform for custom applications, expanding its role beyond just boot management to include embedded programming environments. Such capabilities could inspire further projects that integrate vintage computing concepts with modern hardware standards, fostering innovation in firmware-level software.

Background on UEFI, BASIC, and Retro Computing
UEFI (Unified Extensible Firmware Interface) has become the standard firmware interface for modern PCs, replacing the traditional BIOS. It provides a more flexible and programmable environment, capable of running custom applications during system startup. Meanwhile, BASIC, a programming language developed in the 1960s, remains iconic for its simplicity and accessibility, often used in early personal computers and educational settings. Enthusiasts and hobbyists have long sought ways to run vintage environments on modern hardware, but doing so typically requires emulators or dedicated hardware.
This project stands out because it directly integrates a vintage programming environment into the firmware, a feat that was previously considered complex or impractical. The developer’s approach leverages UEFI’s capabilities to run custom applications, making it possible to execute a BASIC interpreter immediately after powering on the machine, without loading an OS. This represents a convergence of retro computing interests with modern firmware technology, illustrating new possibilities for embedded programming and hardware experimentation.
“Creating a BASIC interpreter that boots directly on UEFI was about exploring the limits of firmware customization and bringing a nostalgic environment into the modern era.”

Technical Limitations and Future Enhancements
It is not yet clear how fully the interpreter supports all BASIC features or how stable it remains across different hardware configurations. The project is still in early stages, and the developer has not yet tested it on diverse UEFI implementations or hardware architectures. Compatibility, security implications, and performance are also areas that remain to be explored. Furthermore, it is uncertain whether the project will be maintained or expanded to include more advanced features or graphical capabilities.

Upcoming Development Goals and Community Involvement
The developer plans to improve the BASIC interpreter’s stability and feature set, potentially adding support for more complex graphics and input methods. They also intend to document the process thoroughly to encourage others to experiment with UEFI-based applications. Community feedback and contributions could lead to broader adoption or even porting the project to different hardware platforms. Future milestones include testing on various UEFI firmware implementations and possibly integrating more vintage computing environments directly into firmware.

Key Questions
Can this BASIC interpreter run on any UEFI-compatible machine?
Theoretically, yes, but practical compatibility depends on the specific UEFI firmware and hardware. The developer has tested it on certain systems, but broader testing is needed to confirm universal compatibility.
Does this project replace a traditional OS or run alongside it?
No, the interpreter runs directly from UEFI during the boot process, before any operating system loads, making it a standalone environment at the firmware level.
What are the potential uses for a UEFI-bootable BASIC interpreter?
Possible uses include educational demonstrations, firmware-level programming experiments, system diagnostics, and hobbyist projects exploring low-level computing environments.
Is the code open source?
Yes, the developer has made the project publicly available, encouraging community experimentation and development.
What are the security implications of running custom applications at firmware level?
Running custom code in UEFI firmware can pose security risks if not properly isolated or verified. Users should exercise caution and understand the potential vulnerabilities involved in flashing custom firmware applications.
