This is a much less expensive mATX variant of the TALOS 2 from the same people.
It runs both little and big endian so both ppc64 and ppc64le. https://www.phoronix.com/scan.php?page=news_item&px=Blackbird-POWER9-Pre-Orders https://raptorcs.com/content/BK1B01/intro.html The only binary blob is the NIC firmware[1], otherwise it is fully open source and has no hardware code signing enforcement so it is entirely yours unlike modern x86 stuff which can't ever be free[2] and has the impossible to disable ME/PSP doing god knows what. OpenPOWER9 CPU's are Made in USA and the board is Made in the USA from US and foreign components so it is much more trustworthy. In terms of speed POWER9 is superior to the offerings from intel/amd or equivilant without x86's spectre/meltdown protections enabled which intel usually dishonestly performs in their benchmarks. [1]It was the best alternative to using an intel nic as there is a large amount of documentation available, people are working on freeing it and the first one to do so gets a free TALOS 2 workstation. [2]New x86 hardware has none of the documentation published that is required to write firmware and it has a variety of black boxes like ME/PSP, boot guard etc designed to prevent you from owning and controlling your hardware.
