A developer has built and shared Thoreau BASIC, a small BASIC interpreter that can boot natively on UEFI systems. This project demonstrates a new way to run classic programming environments on modern hardware. The development is confirmed, but some technical details remain to be clarified.
A developer has released Thoreau BASIC, a lightweight BASIC interpreter that can boot directly on UEFI-based systems. This project enables running classic BASIC environments on modern hardware without an operating system, offering a nostalgic experience for hobbyists and programmers. The developer emphasizes that the interpreter is designed for simplicity, supporting line numbers, immediate mode, graphics, strings, and arrays, reminiscent of early personal computers.
The project was shared on Show HN by the creator, who explained that the goal was to create a small, self-contained BASIC environment that can initialize directly through UEFI firmware. Unlike traditional emulators or OS-dependent implementations, Thoreau BASIC is designed to run as a standalone UEFI application, bypassing the need for an operating system. The developer reports that the interpreter is functional on several UEFI-compatible hardware setups, including common consumer motherboards and laptops.
According to the developer, the implementation is written in C and assembled to run in the UEFI pre-boot environment. The project includes a bootloader, a minimal UEFI application, and the BASIC interpreter code itself. The interpreter supports basic features such as line numbers, immediate execution, simple graphics, string handling, and arrays, aiming to recreate the feel of vintage BASIC environments. The project is open-source, hosted on GitHub, inviting community exploration and potential improvements.
Potential Impact on Vintage Computing and Modern Hardware
This development is notable because it bridges vintage programming environments with modern hardware capabilities. Running BASIC natively on UEFI firmware allows enthusiasts to explore early programming languages without relying on emulators or full operating systems, which can be resource-intensive or complex to set up. It also demonstrates the feasibility of running custom firmware applications that provide rich user environments, potentially inspiring further projects that leverage UEFI for embedded or educational purposes.
For hobbyists, this offers a new way to experiment with classic programming languages directly on current hardware, which could foster renewed interest in retro computing and low-level programming. Additionally, such projects highlight the flexibility of UEFI as a platform for custom applications beyond its traditional role as a firmware interface, possibly influencing future firmware development and embedded systems design.

Background of UEFI and Vintage Programming Environments
UEFI (Unified Extensible Firmware Interface) replaced traditional BIOS systems in modern computers, providing a more flexible and programmable environment for hardware initialization and boot management. While UEFI is primarily used to load operating systems, it also supports running custom applications directly from firmware, enabling lightweight, pre-boot utilities.
Meanwhile, BASIC was a popular programming language in the 1970s and 1980s, often used in early personal computers like the Commodore 64 and IBM PC. Classic BASIC interpreters featured line numbers, immediate mode, and simple graphics, fostering a culture of hobbyist programming. Over time, these environments became obsolete as operating systems and high-level languages took precedence.
Recent efforts have focused on emulating vintage systems or porting old interpreters to modern platforms. However, few projects have successfully integrated vintage programming environments directly into the UEFI firmware, making Thoreau BASIC a notable exception. The developer’s approach leverages UEFI’s capabilities to run custom applications before an OS loads, creating a new avenue for retro-computing experiments.
“My goal was to create a tiny, self-contained BASIC interpreter that can run directly from UEFI firmware, giving users a nostalgic programming environment without needing an OS.”

Technical Limitations and Compatibility Questions
While the developer reports successful testing on several UEFI-compatible systems, detailed information about hardware compatibility, stability, and performance benchmarks remains limited. It is not yet clear how well the interpreter handles complex programs or graphics, or whether it can run on all UEFI firmware implementations. Additionally, the security implications of running custom UEFI applications are still to be evaluated, and the project’s long-term stability is unconfirmed.

Future Development and Community Involvement Opportunities
The developer plans to continue refining Thoreau BASIC, improving compatibility and adding features. They also invite community contributions via the GitHub repository, encouraging testing on diverse hardware and potential porting to other firmware environments like coreboot or OpenEFI. Further development may include expanding graphics capabilities, supporting disk I/O, and integrating debugging tools. The project represents an early step toward more extensive retro-computing projects built directly into firmware.
