About a month ago, I officially unveiled the EndBOX: a retro-style micro-computer designed to run the EndBOX OS. And what is the EndBOX OS, you ask? It’s a small NetBSD system engineered to launch you into an EndBASIC interpreter as fast as possible.
Today, I’m excited to announce the DIY guide to build your very own EndBOX and the first official disk images of the EndBOX OS!
Ready to get started? Head over to the new EndBOX page. There, you’ll find all the details you need:
Components for building both the EndBOX I and EndBOX I Micro.
Instructions on how to download and write the EndBOX OS disk image to an SD card.
Details on configuring the EndBOX OS, which has some unique differences from the EndBASIC you might be used to in your web browser.
Prefer direct downloads? The updated downloads page has direct links to the EndBOX OS disk images. You’ll find versions for the Raspberry Pi (validated on the Pi 3B+ and Pi Zero 2 W) and for arbitrary x86-64 systems. While the x86-64 image has seen limited testing, it could be a fantastic way to breathe new life into an old laptop or desktop computer.
I hope you have a blast building your own little machine!
