@Carlos:
I'm still puzzled by how you figured out the version numbers back then

@Carlos:
The A2 CPU really surprised me and the data looks promising. Unfortunately it doesn't have a SIMD unit, but with a little effort it can be added for sure.

@Carlos:
I had read on the blog of Awilfox (The Cat Fox Life) some time ago that they are working on Devuan. On the Devuan website they also ask for PowerPC/ SPARC/ MIPS hardware: https://devuan.org/os/donate. But in the end I was surprised, because I hadn't heard anything about it for so long.

@Carlos:
Did you overlook my OpenWrt suggestion or is this not really an OS?
https://en.wikipedia.org/wiki/OpenWrt
https://openwrt.org/docs/platforms/start

Available for PowerPC and SPARC. Not sure if SPARC64. I found this:
"1759ea1 conform: XFAIL siginfo_t si_band test on sparc64"
https://openwrt.org/releases/19.07/changelog-19.07.0

@Carlos:
Oh, and I guess there was also an update for WindRiver Linux:
https://github.com/WindRiver-Labs/wrlinux-x/releases

@M4u5:
Ezt láttátok már?

@M4u5:
És hogyan lehet PAL képernyőn színeket gányolni CGA alatt?

@Carlos:
One of the developers of Devuan now has a RaptorCS rig. Dunno if he is willing to port it to big-endian also.

@Carlos:
You are right, the only things I found for OpenWrt and PPC64 are outdated:

@Carlos:
Hey and some new about OpenBSD and PPC64. The good thing, it's be. The bad thing, POWER9 only ...
