TL;DR
A developer has released a BASIC interpreter that can boot on UEFI systems. This allows running classic BASIC environments on modern hardware, highlighting interest in retro computing and low-level programming.
A developer has released a BASIC interpreter that boots directly on UEFI systems, enabling vintage-style programming environments on modern hardware. This development represents a technical achievement in low-level programming and retro computing, and it sparks interest among hobbyists and developers interested in system firmware and legacy languages.
The project, titled ‘Thoreau BASIC,’ is a minimalistic BASIC interpreter designed to run as a UEFI application. The developer, who posted on Show HN, aimed to create a small, simple environment reminiscent of early personal computers, with features such as line numbers, immediate mode, basic graphics, strings, and arrays. Unlike traditional interpreters that run within an operating system, this version boots directly from firmware, bypassing the need for an OS or bootloader.
The implementation leverages UEFI’s capabilities to load and execute code during system startup. The developer wrote the interpreter in C, using UEFI’s firmware interface to initialize and run the environment. This approach demonstrates how low-level system programming can enable vintage software to operate on current hardware, opening possibilities for hobbyists, educators, and enthusiasts of retro computing.
The project is open source, with the code available on a public repository. The developer has shared instructions on how to compile and deploy the interpreter on UEFI-compatible hardware, emphasizing its compatibility with standard x86_64 UEFI firmware. The project is still in early stages but functions as a proof of concept for running a BASIC environment natively on modern firmware.
Potential Impact on Retro Computing and Firmware Programming
This development matters because it demonstrates that vintage programming environments can be integrated directly into modern hardware without relying on an operating system. It opens new avenues for hobbyists to experiment with low-level programming and firmware development, and it provides a platform for educational purposes, illustrating how early computers operated at a firmware level. Additionally, it highlights the flexibility of UEFI as a development platform beyond its typical role in boot management.
By enabling a BASIC interpreter to boot natively, the project also underscores the potential for creating highly customized, minimal operating environments. This could influence future projects aiming to run legacy software or develop security-focused, lightweight firmware-based systems. Overall, it bridges the gap between vintage and modern computing, fostering innovation in firmware-level programming and retro software preservation.

Background on UEFI and Retro Language Projects
UEFI (Unified Extensible Firmware Interface) has become the standard firmware interface for modern PCs, replacing BIOS. It provides a flexible environment for hardware initialization and boot management, with capabilities for running applications directly from firmware. While UEFI applications are typically used for system setup, diagnostics, or boot loaders, some developers explore its potential as a platform for custom software.
Meanwhile, vintage programming languages like BASIC have a nostalgic and educational appeal. Historically, BASIC was one of the first languages accessible to beginners, with implementations on early personal computers. Enthusiasts have long sought ways to run BASIC environments on modern hardware, often through emulators or virtual machines. However, few have managed to run a BASIC interpreter directly from firmware, especially on UEFI systems.
The developer’s project builds on this background, combining low-level firmware programming with retro language environments. It follows a tradition of hobbyist efforts to preserve and explore vintage computing, but with a novel twist: using UEFI as the boot environment for a BASIC interpreter, rather than traditional emulators or OS-based solutions.
“I wanted a small, old-fashioned BASIC interpreter that could run directly on modern hardware without an OS, so I wrote Thoreau BASIC to boot on UEFI.”

Limitations and Compatibility Questions
It is not yet clear how fully functional the interpreter is across different hardware platforms or whether it supports all features of traditional BASIC. The project is still in early development, and extensive testing on various UEFI implementations is ongoing. Compatibility with non-x86 architectures or UEFI firmware variants remains unconfirmed, and performance benchmarks are not yet available.
Additionally, the long-term stability and security implications of running a custom firmware application like this are still unknown, and further development is needed to assess its robustness and safety in different environments.

Future Development and Community Engagement
The developer plans to expand the interpreter’s capabilities, improve compatibility, and provide detailed documentation for broader adoption. They also aim to gather feedback from the retro computing community and test the project on various hardware configurations. Future updates may include graphical enhancements, support for additional BASIC features, and integration with other low-level firmware tools.
Community involvement is expected to grow, with potential collaborations to port the interpreter to other firmware environments or embed it into custom firmware projects. The project’s open-source nature encourages experimentation and contribution from enthusiasts interested in low-level programming, vintage software, and firmware development.

Key Questions
How do I run the BASIC interpreter on my UEFI system?
The developer has provided instructions on how to compile the code and deploy it as a UEFI application. You will need a UEFI-compatible machine and a USB drive or other media to load the interpreter, following the provided setup steps.
Does this project support all features of traditional BASIC?
The current version is a minimal implementation focusing on core features like line numbers, immediate mode, and basic graphics. More advanced features are planned for future updates.
Can this run on non-x86 hardware or ARM-based UEFI systems?
At present, the project is designed for x86_64 UEFI firmware. Compatibility with other architectures has not been confirmed and would require additional development.
What are the security implications of running custom firmware applications like this?
Running custom UEFI applications can pose security risks, especially if obtained from untrusted sources. Users should exercise caution and understand the potential impacts before deploying such software on their systems.
