A programmer has developed Thoreau BASIC, a minimalist BASIC interpreter that can boot directly on UEFI machines. This development allows running vintage-style BASIC environments on modern hardware without needing an operating system. The project is shared on Show HN, sparking interest among retro computing enthusiasts and developers.
A developer has introduced Thoreau BASIC, a minimalist BASIC interpreter that can boot directly on UEFI-based systems. This project enables vintage programming experiences on modern hardware without the need for an operating system, marking a notable achievement in retro computing and low-level programming.
The developer, who posted on Show HN, detailed that Thoreau BASIC is designed to be small, simple, and compatible with UEFI firmware, bypassing the need for traditional OS bootloaders. The interpreter features line numbers, immediate mode execution, simple graphics, string handling, and arrays, emulating classic BASIC environments.
According to the author, the project was motivated by a desire for a lightweight, old-fashioned programming environment that could run directly on modern hardware. The implementation involves writing a custom UEFI application that loads the interpreter into memory and executes it without relying on an operating system kernel. This approach leverages UEFI’s capabilities to run applications at a low level, similar to how bootloaders operate.
The project is shared openly on Show HN, with the developer providing source code and instructions for building and deploying Thoreau BASIC on compatible UEFI systems. Early responses indicate interest from retro computing enthusiasts, hobbyists, and developers curious about low-level system programming.
Potential Impact on Retro Computing and Low-Level Programming
This development demonstrates that it is feasible to run vintage programming environments directly on modern hardware, bypassing traditional operating systems. It opens avenues for educational purposes, hobbyist projects, and preservation of classic computing experiences. Additionally, it showcases the versatility of UEFI firmware as a platform for custom low-level applications, expanding its use beyond standard boot processes.
For developers, Thoreau BASIC provides a lightweight, self-contained environment that can serve as a foundation for further experimentation with direct hardware interaction and firmware-level programming. For enthusiasts, it offers a nostalgic yet functional programming platform that runs natively on current hardware, making it a unique tool for learning and experimentation.

Background on UEFI and Vintage Programming Environments
UEFI (Unified Extensible Firmware Interface) is a modern replacement for BIOS, providing a flexible environment for initializing hardware and launching operating systems. Unlike BIOS, UEFI supports running applications directly from firmware, enabling developers to create custom utilities and tools that operate before an OS loads. This capability has been used for security, diagnostics, and boot management, but rarely for running full programming environments.
Vintage BASIC interpreters, like the original Microsoft BASIC, were designed for early personal computers with simple hardware and no operating system. These environments relied on line numbers, immediate mode, and simple graphics, making them ideal for educational purposes and hobbyist programming. Running such environments on modern hardware typically requires emulators or virtual machines, but Thoreau BASIC aims to run directly on hardware via UEFI.
The idea of booting a BASIC interpreter directly on hardware is not new but has been limited by technical challenges, including hardware compatibility, firmware capabilities, and the complexity of modern UEFI systems. The recent release of Thoreau BASIC demonstrates that with careful development, these barriers can be overcome.
“Thoreau BASIC is designed to be simple, portable, and able to run directly on UEFI firmware, providing a vintage programming experience without an operating system.”

Technical Limitations and Compatibility Questions
It is not yet clear how broadly compatible Thoreau BASIC is across different hardware platforms or UEFI implementations. The developer has provided initial instructions, but extensive testing on various systems is ongoing. Compatibility issues, such as hardware-specific UEFI features or firmware restrictions, may limit widespread adoption. Additionally, the performance and stability of the interpreter under different conditions remain to be fully evaluated. Further development and community feedback are needed to clarify these aspects.

Upcoming Development and Community Engagement
The developer plans to refine Thoreau BASIC, improve compatibility, and document the process for broader community use. They also intend to gather feedback from early adopters to identify hardware-specific issues and optimize performance. Future updates may include support for more complex graphics, additional BASIC features, and possibly porting the interpreter to other firmware environments. Community engagement through forums and collaborative development is expected to play a key role in the project’s evolution.
