Commodore has set up a microsite to help steer you towards its unique vision of a modern operating system. If you head over to commodore.net/closewindows, you will first see a banner image of the Commodore 64X PC with OS Vision. But that is essentially an x86 PC in a C64-style ‘bread bin’ chassis, so don’t worry about the hardware.
Kind of. Apparently the rights are a mess and owned by 3 different companies, one of which is Commodore, although it seems like the current version of AmigaOS is owned by a different company.
The most recent version of AmigaOS is 4.1 which was released in 2014, and requires a PowerPC CPU. It’s kind of hard to argue that’s a modern OS, although apparently a 4.2 release is in the works. The dependency on PowerPC is kind of a problem at this point as their CPUs have stagnated and it’s hard to find any modern ones that aren’t custom CPUs for game consoles (and even then mostly old game consoles).
Additionally there’s the problem of software availability. The new Commodore OS is just a tweaked Linux install so it gets all the Linux software essentially for free. AmigaOS on the other hand is legitimately its own OS and therefore only runs Amiga software.
Wasn’t the Xbox 360 a PowerPC machine?
Yes, but it’s also 20 years old now and has been discontinued for almost a decade. Likewise the Wii had a PowerPC CPU in it. None of the current consoles use PowerPC, They’re either x86 (Xbox One and PlayStation 5) or ARM (Switch 2).
