HoloISO [1] is as close as you can get to SteamOS 3 until Steam ships the official version. From the README : "Is this official? No, but it may as well be 99% of the way there. The code and packages, are straight from Valve, with zero possible edits, and the ISO is being built on the official Steam Deck recovery image, running inside a QEMU instance." You can watch it run on a variety of hardware on YouTube. [1]: https://github.com/theVakhovskeIsTaken/holoiso https://github.com/theVakhovskeIsTaken/holoiso
