A month ago, I announced of a "little box" I've been working on to run EndBASIC, similar to the machines we played with in the 1980s. The box was briefly discussed in https://news.ycombinator.com/item?id=44253065 and I wasn't quite ready to properly launch it.
Today, I'm still not ready to actually build and ship this box myself as I was previously thinking (and I'm not sure I'll even try to embark on that journey!), but I have finished preparing DIY instructions to build your own little machine.
AND, as part of this, I've released the disk image with the tailored OS for the Raspberry Pi to run a BASIC system right at boot. In case you are curious, the OS is, essentially, a minimal NetBSD system customized with a build of the EndBASIC interpreter that leverages NetBSD APIs directly, bypassing the need for X11 to offer you a console very early in the boot.

Hope you enjoy it.
