TL;DR
A software developer has announced a new BASIC interpreter that boots natively on UEFI systems. This development allows running a classic programming environment on modern hardware, bridging retro computing with current technology. The project is in early stages, with detailed performance and compatibility tests pending.
A developer has introduced Thoreau BASIC, a vintage-style BASIC interpreter capable of booting directly on UEFI-based machines. This project enables users to run a classic programming environment natively on modern hardware, a feat that bridges the gap between retro computing and contemporary firmware standards. The developer’s goal is to create a small, simple environment reminiscent of early personal computing, but with the convenience of modern UEFI firmware.
The project was shared on Show HN by the developer, who explained that Thoreau BASIC is designed to boot directly from UEFI firmware, bypassing the need for an operating system. The interpreter supports line numbers, immediate mode, simple graphics, strings, and arrays, emulating the classic BASIC experience. The developer emphasized that the primary motivation was to create a minimal, easy-to-understand environment that can run on any UEFI-compatible hardware.
According to the developer, the implementation involves writing a small UEFI application that loads the BASIC interpreter into memory and executes it directly. This approach leverages UEFI’s capabilities to run custom code during system startup, making it possible to run BASIC programs without an OS. The project is still in early development, with plans to improve hardware compatibility and add features like disk I/O and networking support in future versions.
While the project is currently a proof-of-concept, it has garnered interest from enthusiasts in retro computing and firmware hacking communities. The developer noted that the code is open-source and available for others to experiment with, aiming to foster a community around native booting BASIC environments.
Potential Impact on Retro Computing and Firmware Development
This development is significant because it demonstrates that vintage programming environments can be run directly on modern hardware without the need for an operating system. For enthusiasts, this opens new avenues for exploring retro programming and firmware hacking, providing a platform to run classic code in a native environment. It also showcases how UEFI firmware can be leveraged for custom applications beyond standard boot processes, potentially inspiring further innovations in firmware-level programming.
Moreover, the project underscores the flexibility of UEFI as a platform for custom applications, which could lead to new uses in embedded systems, security research, or educational tools. By enabling a vintage environment on modern hardware, it preserves the experience of early personal computing while utilizing current technology’s capabilities.

Background on UEFI, BASIC, and Retro Computing
The BASIC programming language, developed in the 1960s, became a staple of early personal computers, offering an accessible environment for beginners and hobbyists. Over the decades, it evolved into various dialects, remaining popular among retro computing enthusiasts. Meanwhile, UEFI (Unified Extensible Firmware Interface) replaced the traditional BIOS in most modern PCs, providing a flexible, programmable firmware interface that initializes hardware during startup.
Traditionally, running BASIC required an operating system or emulator; native booting was rare due to the complexity of interfacing directly with firmware. However, recent advances in UEFI development and open-source firmware projects have made it possible to run custom applications directly at system startup. This context sets the stage for the developer’s achievement in creating a UEFI-compatible BASIC interpreter, a feat combining retro programming with modern firmware capabilities.
Prior efforts in firmware hacking have explored UEFI shell scripting and custom bootloaders, but a fully functional BASIC interpreter that boots directly on UEFI systems marks a novel step forward. The developer’s approach is aligned with a broader interest in minimal, self-contained computing environments that can operate independently of full operating systems.
