TL;DR
A programmer has developed a BASIC interpreter that can boot on UEFI systems, combining old-school programming with modern firmware. This project demonstrates the feasibility of running vintage interpreters on current hardware, with potential educational and hobbyist applications.
A developer has introduced Thoreau BASIC, a BASIC interpreter capable of booting directly on UEFI firmware. This project allows vintage-style programming environments to run on modern hardware without an operating system, highlighting both technical achievement and potential educational value.
The developer, who posted their project on Show HN, built Thoreau BASIC to run independently on UEFI firmware, bypassing the need for an OS. The interpreter features line numbers, immediate mode, simple graphics, strings, and arrays, emulating classic BASIC environments. The project aims to demonstrate that vintage interpreters can operate directly on contemporary hardware, opening avenues for hobbyists and educators interested in low-level programming and computer history.
According to the developer, the implementation leverages UEFI’s capabilities to load and execute code during the firmware phase, before the OS loads. This approach involves writing a UEFI application that initializes the interpreter environment and provides a minimal interface for BASIC programs. The project is open-source, with the code available for community review and experimentation.
While the project is still in early stages, initial tests show that Thoreau BASIC can run simple programs, including graphics and string manipulation, directly on UEFI firmware. The developer emphasized that this work is primarily a proof of concept, with room for optimization and feature expansion in future iterations.
Implications for Vintage Computing and Firmware-Level Programming
This development is significant because it demonstrates that classic programming environments like BASIC can be revived and run directly on modern hardware without an operating system. It offers a new way to explore low-level firmware programming and provides educational opportunities for understanding computer boot processes. Additionally, it could inspire hobbyists to develop other vintage interpreters or programming environments that operate at the firmware level, bypassing traditional OS layers.
Furthermore, this project showcases the flexibility of UEFI firmware as a platform for custom applications, which could lead to innovative uses beyond standard boot management. It highlights the potential for more embedded or specialized software to run directly during system startup, opening new avenues for firmware-level customization and experimentation.

Background on UEFI and Vintage Programming Environments
UEFI (Unified Extensible Firmware Interface) replaced traditional BIOS as the standard firmware interface for modern PCs, offering a more flexible and programmable environment. Unlike BIOS, UEFI supports applications that can run during system startup, enabling custom software to be executed before the OS loads.
Vintage programming environments like BASIC have historically been used on early personal computers with dedicated hardware and firmware. As hardware evolved, these environments migrated into software within operating systems, losing their direct hardware interaction. Recent hobbyist projects aim to revive these environments, often through emulators or specialized hardware, but running them directly on modern hardware remains a challenge.
This project by the developer builds on the idea of leveraging UEFI’s capabilities to run a BASIC interpreter without an OS, effectively creating a bridge between vintage programming and modern firmware technology. The approach echoes earlier efforts to run small, self-contained programs at boot time, but with a focus on a full interpreter environment.
“Thoreau BASIC is a proof of concept that shows vintage interpreters can operate directly during system startup, opening new possibilities for low-level programming and education.”

Unresolved Technical Challenges and Future Development
It is not yet clear how fully stable or feature-complete Thoreau BASIC will become, as the project is currently in early stages. Performance metrics, compatibility with complex programs, and security considerations of running interpreters at the firmware level remain to be explored. Additionally, the scalability of this approach for more complex environments or other interpreters is still uncertain.
Next Steps for Enhancing and Expanding the Project
The developer plans to refine Thoreau BASIC, improve its stability, and add features such as file handling and enhanced graphics. Community feedback and contributions are encouraged to expand its capabilities. Future milestones include supporting more complex BASIC programs and exploring other vintage interpreters or programming languages that could run directly on UEFI firmware.
Further testing on different hardware platforms and benchmarking performance will help assess the practicality of broader adoption. The project’s open-source nature ensures ongoing development and potential integration into educational tools or hobbyist projects.
