TL;DR
A developer has built a BASIC interpreter capable of booting on UEFI machines, enabling retro programming environments on modern hardware. The project aims to combine old-school coding with current technology, with potential educational and hobbyist applications.
A developer has created a BASIC interpreter that boots directly on UEFI systems, bypassing traditional operating systems to run natively on modern hardware. This project demonstrates the feasibility of running vintage programming environments on contemporary machines, offering new possibilities for hobbyists, educators, and retro computing enthusiasts.
The developer, who posted their project on Show HN, has designed a minimal BASIC interpreter that loads directly from UEFI firmware, eliminating the need for an OS. The interpreter features line numbers, immediate mode execution, simple graphics, string handling, and arrays, emulating classic BASIC environments. The project involves writing a UEFI application in C that initializes hardware, loads the interpreter into memory, and executes it as a standalone program.
The project aims to preserve and revive vintage programming styles, providing a lightweight, self-contained platform that can run on modern hardware without an operating system. The developer emphasizes that the interpreter is a proof of concept, demonstrating that UEFI firmware can host custom applications beyond standard bootloaders and firmware diagnostics.
Why Running BASIC on UEFI Matters for Computing
This development is significant because it shows that vintage programming environments can be integrated directly into modern firmware, bypassing traditional operating systems. It opens avenues for hobbyists to experiment with old-school coding styles on current hardware, and offers educators a tool to teach programming fundamentals without relying on complex OS environments. Additionally, it demonstrates the flexibility of UEFI firmware, which is increasingly used for custom applications beyond booting operating systems.
By enabling BASIC to run natively, the project preserves a programming style that emphasizes simplicity, immediacy, and direct hardware interaction. It also highlights the potential for creating minimal, self-contained computing environments that are portable and less dependent on bulky OS stacks, which could have implications for embedded systems and security-focused applications.

Background and Technical Foundations of UEFI and Vintage Programming
UEFI (Unified Extensible Firmware Interface) has become the standard firmware interface for modern computers, replacing the older BIOS system. Unlike BIOS, UEFI supports complex applications, secure boot, and graphical interfaces, making it a flexible platform for custom software development. Traditionally, UEFI is used to initialize hardware and load operating systems, but it can also host standalone applications or firmware utilities.
The idea of running vintage programming languages like BASIC on modern hardware is not new, but doing so directly from firmware is rare. Historically, BASIC interpreters ran within operating systems or as standalone programs on PCs and mainframes. The challenge has been to port such interpreters to run in the constrained environment of UEFI, which has limited resources and requires applications to be written in C or similar languages compatible with UEFI standards.
The developer’s project builds on existing knowledge of UEFI application development and retro programming environments, combining them into a single, bootable package. This approach leverages UEFI’s ability to run custom applications at boot time, providing a lightweight, OS-free environment for BASIC programming.
“Creating a BASIC interpreter that boots directly on UEFI was a challenge, but it shows how flexible firmware can be for custom applications.”

Limitations and Technical Challenges Still to Address
While the project successfully boots and runs a BASIC interpreter on UEFI, it is still in early development. Performance, hardware compatibility, and feature completeness are areas that require further testing. The developer has not yet demonstrated full graphics capabilities or extensive input handling, which are essential for a complete BASIC environment.
Additionally, it remains unclear how well this approach scales across different hardware architectures or UEFI implementations, as compatibility issues could arise. The security implications of running custom UEFI applications also need evaluation, especially regarding secure boot policies.
Next Steps for Development and Community Engagement
The developer plans to refine the interpreter, improve hardware compatibility, and expand features such as graphics and file I/O. They also intend to document the development process and share the source code openly, encouraging community contributions. Future work may include porting the interpreter to other firmware environments or integrating it with existing bootable media.
Community feedback and testing will be critical to identify bugs and optimize performance. The project aims to serve as a foundation for further exploration of vintage programming environments on modern hardware, potentially inspiring similar projects or educational tools.
Key Questions
Can this BASIC interpreter run on any UEFI-compatible hardware?
It is designed to work on UEFI systems that support the necessary application features, but compatibility across different hardware and firmware implementations is still being tested.
Does this project require secure boot to be disabled?
Disabling secure boot may be necessary depending on the firmware, as custom UEFI applications sometimes conflict with secure boot policies. The developer recommends checking firmware settings before testing.
Can I modify or extend this BASIC interpreter?
Yes, the source code is planned to be released openly, allowing others to customize or expand its features, provided they are familiar with UEFI development and C programming.
What are the practical uses for running BASIC directly from UEFI?
Practical applications include educational demonstrations, hobbyist experimentation, and preserving vintage programming styles in a modern, minimal environment without relying on full operating systems.
Will this project support graphical programs or advanced features?
The current version focuses on core BASIC features; future updates may include graphics and file system support, but these are still under development.
