For those of us who live the POWERful life.
Ideally focusing on modern OpenPOWER hardware (libre-SoC, Microwatt, POWER9) but you’re probably more likely to have a PowerBook or Power Mac laying around, and those are welcome too, as are RS/6000s, ThinkPad Power series, Motorola PowerStack, and Acube’s stuff.
Linux 5 is still being compiled for as low as PowerPC 603, and of couse POWER ISA 3.0 is well supported as the OpenPOWER Foundation is a subsidiary of the Linux Foundation.
Hopefully, whether Framework themselves do it or someone else (probably Acube) does, hopefully one day an ISA 3.0 compatible OpenPOWER board gets released for the Framework.
For now…
there’s always the classics.
I’m currently saving up for a Blackbird mainboard and four core CPU, I have the rest of the build besides it.
