The idea was to make a PC but with a PowerPC CPU in it, and it failed because only IBM/Moto built hardware with it and Apple rejected it. CHRP was the successor (and what modern PPC hardware is based on, to some extent with hypervisors and all leading to PowerNV coming out as yet another PPC standard for Linux only boxes).
Yet CHRP was only used by IBM, because Apple also stonewalled the release of machines adherent to it until Steve Jobs came back, PPC Macs had their own weird Open Firmware implementation, and when IBM made the latest OpenPOWER push they chose to create yet another standard that was "bare metal" and not hypervisored like IBM hardware and the Xbox 360/PS3 are, hence PowerNV.
@YTFoidLover1488@poa.st@atlas_core@pl.starnix.network NetBSD is a meme, especially if you run the non-x86 ports because there are some ports that just don't work, have bitrotted code or other issues, and everything is cross compiled.
One example of this is the PReP port of NetBSD (for 90s IBM PowerPC desktops). For a while, the installer script has been generating floppies far too big for 1.44mb, and the last version with disk images of a proper size was made in 2002! Furthermore the main limiting factor for a netboot is 2mb, meaning that you can't even netboot the machine with the latest kernel.
The Raptor Blackbird might as well be irrelevant when ARM server boards cost around the same, come with a CPU, and have a vastly brighter future. There's also no cheap PPC SBCs and even the SOCs used for Amiga boxes by boomers cost more.
@Pawlicker@atlas_core@YTFoidLover1488 One notable vendor missing from your Mac clone list: Tatung, one of the big vendors in Taiwan who seemed to like having their fingers in every pie (they're the only vendor I'm personally aware of to have done PC compatibles, licensed Macintosh clones, *and* SunOS-compatible SPARC workstations)
You can actually boot and run ARC on those machines, while Motorola had the ARC in ROM if you flashed it, like some of the Alphas did. It's just like with ARC on Alpha/MIPS, only used for Windows NT.
Someone on fedi was trying to port Windows NT to PowerBooks using something like this.
But there's old IBM documents explaining CHRP and PReP where the goal was to actually have a universal PPC box that would run Windows, MacOS, and UNIX and could be tweaked. Of course the problem is it was IBM and this was the 90s when Intel was breaking every antitrust law in the book to gain dominance, on top of Microsoft absolutely insisting that computers ran Windows and Apple being controlling of a cloning program that was already under pressure from MS.
I heard the last reason is why the only Mac clones were built by a startup, Pioneer (who normally didn't make computers), the CPU vendor for Macs, and Mac accessory vendors (UMAX, Radius, and DayStar were Mac accessory vendors). Also every Mac clone was based on a pre-existing Mac model, including the Tanzania design (which was designed to among other things, work with PC floppy drives and had PS/2 and VGA ports on clones).
