TL;DR
A software developer has announced a new BASIC interpreter capable of booting on UEFI systems. This development allows running vintage-style BASIC environments on modern hardware, blending old programming paradigms with current technology. The project is in early stages but has garnered interest from hobbyists and retro computing enthusiasts.
A developer has introduced Thoreau BASIC, a BASIC interpreter designed to boot directly on UEFI firmware on modern computers. This project enables running a vintage programming environment on current hardware without the need for emulators or legacy BIOS systems, marking a significant technical milestone in retro computing and system programming.
The developer, who goes by the username ‘showhn’, announced the project on the Hacker News platform, emphasizing that the interpreter is small, simple, and designed to run on UEFI-based systems. Unlike traditional BASIC interpreters that run within an operating system, Thoreau BASIC is built to initialize directly from the system’s firmware, bypassing the need for an OS or emulator. The project aims to recreate a classic programming environment with line numbers, immediate mode, simple graphics, string handling, and arrays, reminiscent of vintage BASIC interpreters from the 1980s.
The interpreter is written in low-level code, likely C or assembly, and leverages UEFI’s boot services to load and execute. The developer has shared source code and detailed documentation, encouraging others to experiment with or extend the project. While the project is still in early development, initial tests confirm that it can successfully boot on some UEFI systems and run basic BASIC programs, including simple graphics and string manipulations.
Impact of a Native UEFI BASIC Interpreter
This development matters because it bridges vintage programming environments with modern hardware architectures. Running BASIC directly on UEFI firmware eliminates the need for emulators or legacy BIOS support, which are often cumbersome or limited on current systems. It opens avenues for hobbyists, educators, and retro computing enthusiasts to explore classic programming paradigms on contemporary hardware, fostering preservation and experimentation. Additionally, it demonstrates the potential for minimalistic, firmware-level programming environments that can operate independently of operating systems, which may have implications for embedded systems or security-focused firmware development.

Background: Retro Computing and Firmware-Level Programming
Retro computing enthusiasts have long sought ways to run vintage operating systems and programming environments on modern hardware. Traditionally, this has involved emulators or legacy BIOS modes, which are increasingly unsupported or deprecated in newer systems. UEFI, the modern firmware interface replacing BIOS, offers a more flexible and standardized environment but is typically used to load operating systems rather than run standalone interpreters. Few projects have successfully created firmware-level programming environments that boot directly on UEFI, making this project a noteworthy step in that direction.
Previous efforts in this space include minimal bootloaders and custom firmware projects, but none have achieved a full BASIC interpreter that boots directly on UEFI. The developer’s approach aligns with ongoing interests in minimalistic, hardware-embedded programming environments, which could serve educational, hobbyist, or even security research purposes.
“My goal was to create a small, simple BASIC interpreter that can run directly from UEFI firmware, enabling vintage programming environments on modern hardware.”

Unresolved Technical Challenges and Compatibility Limits
It is not yet clear how widely compatible the interpreter will be across different hardware configurations or UEFI implementations. The developer reports initial success on select systems but has not confirmed full compatibility or performance benchmarks on a broad range of hardware. Additionally, the stability and security implications of running firmware-level interpreters are still under assessment, and some features, such as complex graphics or networking, may require further development.
