TL;DR
A programmer has developed a BASIC interpreter capable of booting on UEFI systems. This allows running classic BASIC programs natively on modern hardware, blending retro computing with current technology. The project is shared on Show HN and is still in early stages.
A developer has successfully built and demonstrated a BASIC interpreter that boots directly on UEFI systems, marking a notable achievement in retro computing and low-level programming. This development enables users to run classic BASIC programs natively on modern hardware, bridging vintage software environments with current firmware standards. The project, shared on Show HN, highlights an innovative approach to hobbyist and educational computing, and it is still in early testing stages.
The developer, who goes by the handle ‘Thoreau’, announced on Show HN that they have created a small, self-contained BASIC interpreter that can initialize directly from UEFI firmware. Unlike traditional emulators or virtual machines, this interpreter loads during the system’s boot process, bypassing the need for an operating system. The project aims to recreate the experience of vintage BASIC environments, complete with line numbers, immediate mode, simple graphics, strings, and arrays, all running natively on modern hardware.
The implementation involves writing a minimal UEFI application that initializes hardware, loads the BASIC interpreter from firmware, and provides a command-line interface for running BASIC programs. The developer emphasized that the goal was to create a lightweight, self-sufficient environment that retains the nostalgic feel of early personal computing while leveraging the security and flexibility of UEFI firmware. The code is available publicly, and initial tests show it can successfully boot on several UEFI-compatible motherboards.
Potential Impact on Retro Computing and Education
This development matters because it demonstrates a feasibility of running vintage programming environments directly on modern hardware without relying on emulators or full operating systems. It opens opportunities for hobbyists to experiment with low-level firmware programming, for educators to teach computer architecture and firmware design, and for preserving classic programming languages in a native form. Additionally, it showcases how modern firmware standards like UEFI can host custom applications, expanding their use beyond typical bootloaders or firmware utilities.

Background on UEFI and Vintage BASIC Environments
UEFI (Unified Extensible Firmware Interface) replaced traditional BIOS in most modern PCs, providing a standardized, flexible interface for hardware initialization and boot processes. While UEFI supports custom applications, few have explored running complex interpreters or programming environments directly within firmware. Meanwhile, BASIC, a programming language popularized in the 1970s and 1980s, has largely disappeared from mainstream use but remains beloved by hobbyists and educators for its simplicity and historical significance.
Prior efforts to recreate BASIC environments have focused on emulators, virtual machines, or minimal OS-based implementations. The novelty here is the direct boot approach, which eliminates dependencies on operating systems, offering a more authentic vintage experience and potentially more efficient execution. The developer’s project is among the first known attempts to combine these elements into a single, UEFI-native application.
“Creating a BASIC interpreter that boots directly on UEFI was a challenge, but it shows how flexible modern firmware can be for hobbyist projects.”

Technical Limitations and Compatibility Questions
It is not yet clear how broadly compatible the BASIC interpreter is across different UEFI implementations and hardware configurations. The developer has tested on several systems, but comprehensive testing across diverse hardware remains ongoing. Additionally, performance benchmarks, stability over extended use, and support for advanced graphics or peripherals are still under development. The project is in early stages, and further refinement is expected.

Next Steps for Development and Community Involvement
The developer plans to expand compatibility, improve stability, and add features such as better graphics and peripheral support. They also intend to create documentation and tutorials to help others build or adapt similar projects. Community feedback and contributions are encouraged, and future updates may include porting the interpreter to other firmware standards or integrating it with custom bootloaders. The project aims to serve as a platform for experimentation with low-level programming and firmware-based environments.

Key Questions
Can I run my own BASIC programs with this interpreter?
Yes, once the interpreter is installed and booted, you can load and run BASIC programs in the environment, similar to vintage systems.
Does this require specific hardware or firmware versions?
The developer has tested on several UEFI-compatible motherboards, but full compatibility across all hardware is still being evaluated. It generally requires UEFI firmware with minimal restrictions.
Is the source code available for modification?
Yes, the project is publicly shared, and the developer encourages community involvement and customization.
How does this compare to running BASIC in an emulator?
This approach offers a more authentic vintage experience by running directly on hardware, avoiding emulation overhead and providing a genuine low-level environment.
What are the main limitations at this stage?
Current limitations include limited hardware compatibility, incomplete peripheral support, and ongoing stability testing. Performance benchmarks are also pending.
