Mirari: PowerPC alive in 2025?
It looks like a new, affordable PowerPC mainboard for AmigaOS4 and MorphOS (and Linux) is in development, nearing public release.
The beginning of project "Mirari" dates back to around May 2024. The first tangible news appeared a couple of weeks ago, at the end of April 2025, when "Mirari" specifications were announced on the "Hardware" channel of the Amigans Discord server, which got mentioned on long-running Amiga news website amiga-news.de.

It says that at that point in time, five out of five ordered prototype boards were already working, running Linux, and undergoing "burn-in" testing.
"Mirari" is a MiniATX form-factor mainboard...
...for T10x2 (e5500 cores) and T2081 (e6500 cores) PowerPC processors, at up to 1.8GHz
...with DDR3 SO-DIMM RAM slot
...PCI-express slots (x1, x4, x16), SATA, NVMe, USB 2.0 and 3.2, Gigabit-Ethernet
...192kHz/24bit analog audio, S/PDIF digital audio
...9-pin RS232 port
...and MicroSDCard slot (for booting)
...among a couple of other things. That sounds very good so far, and indeed, on their website (see below) we can find more details, including not only 3D-renderings of the board, but also a round of actual photographs from the development and testing stage of "Mirari".
A couple of days ago, Retro-computing enthusiast and YouTuber TJ Ferreira published a video, in which he takes a look at the information available on Mirari's website. It's a nice watch with some additional commentary about the facts & features - or, if you prefer a little more first-hand expericence, click here for "Mirari" website:
