AROS, the open source Amiga OS-compatible operating system, now has images available for the Raspberry Pi 3 (although some people state it also works on the Pi 4), in both 32bit and 64bit versions. According to the AROS team, they are quite stable, but not yet complete, so do know what you’re getting into. Dan Wood posted a YouTube video about these new images, providing much more insight into how well they work if you want more insight into how well they work.
The images are, of course, the basic AROS operating system, so expect a rather barebones experience. If you’re used to some of the AROS distributions for x86, which come loaded with software and customisations, these images will feel quite bare to you. It’s going to take some time to port over all of these applications and customisations to the ARM version of AROS, but if and once that happens, I expect more complete images to appear as well.
Great news for AROS and the Amiga community in general.

Shame that AROS has been turned into Claudeslop recently… 13 commits from the slop machine in recent months (most of them in July) https://slopscan.ava.pet/repo/https%3A%2F%2Fgithub.com%2Faros-development-team%2FAROS
