TL;DR
A programmer has developed and shared Thoreau BASIC, a minimal BASIC interpreter that can boot on UEFI-compatible machines. This allows running a classic programming environment on modern hardware without an operating system. The project is shared on Show HN and signals interest in retro computing and low-level programming.
A developer has introduced Thoreau BASIC, a small, self-contained BASIC interpreter that can boot directly on UEFI-compatible machines. This project enables vintage-style programming environments on modern hardware without requiring an operating system, marking a notable achievement in low-level software development and retro computing.
The developer, who goes by the name on Show HN, described building Thoreau BASIC to recreate the experience of early personal computing, with features such as line numbers, immediate mode execution, simple graphics, string handling, and arrays. The key innovation is that the interpreter is designed to load and run directly from UEFI firmware, bypassing the need for an OS or bootloader.
The project was shared publicly on Show HN, where the creator explained that the interpreter is small and simple enough to fit into a minimal UEFI environment. It demonstrates the feasibility of running a complete programming environment without an underlying OS, which could have implications for embedded systems, hobbyist projects, and educational tools. The developer emphasized that the code is open source, inviting others to experiment and extend the project.
While the project is functional in preliminary tests, the developer notes that it is still in early stages, with ongoing work to improve stability, add features, and optimize performance. The current implementation supports basic line execution, graphics, and string operations, but more complex features like file I/O and networking are not yet integrated.
Impact of UEFI Bootable BASIC on Modern Computing
This development is significant because it demonstrates that a complete programming environment can be run directly from firmware, without the need for a traditional operating system. For hobbyists and educators, this opens opportunities to explore computing fundamentals, low-level programming, and hardware interaction in a simplified setting. It also highlights the potential for embedded systems that require minimal software layers, reducing complexity and attack surface.
Furthermore, the project rekindles interest in retro computing by providing a nostalgic environment that runs on current hardware. It underscores the versatility of UEFI firmware as a platform for custom software, expanding the scope of what can be achieved without conventional OS dependencies. This could inspire further projects that leverage UEFI for specialized or educational applications, or for creating secure, minimal boot environments.

Background and Previous Efforts in UEFI and BASIC Emulation
The idea of running BASIC interpreters on modern hardware is not new; previous efforts have focused on emulators, virtual machines, or software that runs within existing operating systems. However, directly booting a BASIC interpreter from UEFI firmware is a novel approach, made possible by recent advances in UEFI development kits and open firmware tools.
Historically, BASIC was a popular language in the 1980s, often bundled with early personal computers like the IBM PC and Commodore 64. Emulators and interpreters have since recreated that environment in software, but few projects have successfully integrated a BASIC interpreter into the firmware layer itself. The recent Show HN post marks a shift toward minimal, hardware-level implementations, inspired by hobbyist interest in low-level programming and retro computing revival.
Prior to this, some efforts have involved running minimal operating systems or bootloaders that include BASIC interpreters, but these are typically larger and depend on more complex software stacks. The new project aims to strip down to the essentials, showcasing the feasibility of a self-sufficient, firmware-based environment.

Current Limitations and Future Development Challenges
It is not yet clear how stable or complete the current implementation is, as the developer notes ongoing work. Features such as file handling, networking, and advanced graphics are not yet supported, and performance may vary on different hardware configurations. The project’s scalability and security implications are also still to be explored, especially for use beyond hobbyist experimentation.
