TL;DR
A programmer has developed a BASIC interpreter capable of booting on UEFI machines. This innovation allows running classic BASIC programs natively on modern hardware, merging retro computing with current technology. The project is shared on Show HN, highlighting its technical achievement and potential applications.
A developer has announced the creation of a BASIC interpreter that boots directly on UEFI systems, marking a significant step in retro computing on modern hardware. This project allows users to run classic BASIC programs natively without needing legacy BIOS or emulators, bridging vintage programming environments with current technology. The developer shared this achievement on Show HN, emphasizing its technical novelty and potential for enthusiasts and developers interested in low-level programming.
The project involves a custom-built BASIC interpreter that can be loaded and executed during the UEFI boot process. UEFI (Unified Extensible Firmware Interface) is the modern replacement for BIOS, providing a flexible, standardized interface for firmware. Traditionally, running old programming languages like BASIC required emulators or legacy hardware, but this interpreter enables direct execution at the firmware level, making it possible to write and run BASIC programs immediately after system startup.
The developer, whose identity has not been publicly disclosed, explained that the goal was to create a small, simple environment reminiscent of classic BASIC interpreters—featuring line numbers, immediate mode, simple graphics, strings, and arrays. The project was motivated by a desire to explore minimalistic programming environments and to demonstrate the feasibility of running such environments directly on current hardware without additional layers of software or OS dependencies.
According to the developer, the interpreter is written in low-level code compatible with UEFI’s specifications, and it is designed to be lightweight, occupying minimal space in firmware memory. The process involves integrating the interpreter into the UEFI firmware, allowing users to select it as a boot option, and then interact with BASIC programs in a straightforward manner. The project is available on Show HN, inviting feedback and collaboration from the community.
Implications for Retro Computing and Firmware Development
This development is significant because it demonstrates that vintage programming environments like BASIC can be run directly at the firmware level, bypassing traditional operating systems. It opens possibilities for retro computing enthusiasts to experiment with classic languages on modern hardware without emulators or legacy systems. Additionally, it showcases the flexibility of UEFI firmware, which is increasingly used for custom low-level projects, including embedded systems and security research.
For developers, the project illustrates the potential for building lightweight, self-contained interpreters that can operate in the early boot stages of a system. It also raises questions about the security implications of running custom code during firmware initialization, an area that requires careful consideration. Overall, this project bridges the gap between vintage programming and contemporary firmware technology, highlighting new avenues for experimentation and education.

Background on UEFI, BASIC, and Firmware Projects
UEFI (Unified Extensible Firmware Interface) has become the standard firmware interface for most modern PCs, replacing BIOS with a more flexible and programmable environment. While UEFI is primarily used for hardware initialization and boot management, it also supports custom applications and drivers, enabling advanced projects like this BASIC interpreter.
BASIC, developed in the 1960s, was once a ubiquitous programming language for beginners and hobbyists. Over the decades, it has largely been replaced by more modern languages, but it remains popular among enthusiasts for its simplicity and historical significance. Running BASIC directly on hardware has traditionally required emulators or legacy BIOS-based systems, making this project notable for its direct approach.
Previous efforts to run vintage languages on modern systems often relied on emulation layers, virtual machines, or dedicated hardware. This project stands out because it integrates the interpreter into the firmware, allowing immediate execution during system startup.
The developer’s motivation was partly driven by nostalgia and partly by curiosity about minimalistic programming environments, aiming to demonstrate that classic languages can still find a place on contemporary hardware.

Technical Challenges and Security Considerations
It is not yet clear how robust the interpreter is across different hardware configurations or how easily it can be extended to support more complex BASIC features. Details about security measures to prevent firmware vulnerabilities introduced by custom code are still emerging. Running code at the firmware level inherently carries risks, and the developer has not yet disclosed comprehensive safety protocols or sandboxing measures.
Further testing is needed to determine compatibility with various UEFI implementations and hardware architectures, and whether this approach could be adopted for broader applications beyond hobbyist projects.
Upcoming Development and Community Feedback
The developer plans to refine the interpreter, improve compatibility, and possibly add more features like file I/O and advanced graphics. Community feedback on Show HN is encouraged to identify bugs and suggest enhancements. Future updates may include security hardening and documentation to facilitate wider adoption.
Additionally, the project may inspire similar firmware-level interpreters for other vintage languages or experimental environments, expanding the scope of what can be achieved during early system initialization.
Key Questions
Can I run my own BASIC programs with this interpreter?
Yes, once set up, you can load and run BASIC programs directly during UEFI boot, provided the programs are compatible with the interpreter’s features.
Is this safe to use on my main system?
Running custom firmware code carries inherent risks, especially if security measures are not fully implemented. Use caution and test in controlled environments.
Does this work on all UEFI systems?
Compatibility may vary depending on hardware and firmware implementations. Further testing is needed to confirm broad support.
