An A1/Pegasos makes "much sense" the moment you replaced all things Amiga with much more powerful components from 15 years later making the Axx00 an glorified keyboard controller.
(same reason I don't get all the buzz about the Vampire)
Now Phase5PPC+Permedia/PCI does already fall into that category but is acceptable due to being released in a different time.
Bout having a Sonnet-PPC in an MorphOS-NG running x86-64, just start MorphOS3.x in QEMU and be done with it.
I kind of get Vampire, until you reach Vampire4, where attachment to legacy hardware is redundant as all functionality now resides in the FPGA and it can exist as a stand alone system.
And yes, QEMU is beginning to look like the solution for running current NG software.
Although the first project that intrigues me is the idea of emulating the SAM460 and the X5000 on a PCIe PowerMac G5 11,2.
And I'd assume similar emulations could been done easily on a Power 9 based platform, possible multiple instances of OS', one or more than one type.
How about ALL Amigoid OS running on one platform with plenty of threads to spare.
Since Power 9 has PPC compatibility, our current NG OS' and hardware (outside of AROS) would be easier to emulate and require less cpu power than similar emulation via X64.
We would need something that would run above these emulations, provide a common user interface and a method of compositing the various display windows, and accessing the hypervisor.
Possibly a variant of Linux.
OR Bigfoot, Keiro and a few other talented programmers could expand on Ambient and and an SMP enabled kernel could be provide the core of something beyond MorphOS that manages everything, and provides an environment for 64 bit code with memory protection and all the modern features we are currently missing.
Nothing like that is likely to happen, as we are all mired in this slow death march of evolution that is one step from completely frozen, dragging around the corpse of a legacy API.
But you're right, one system would do.
I guess I'll start exploring the options right now on my X64 hardware and my 11,2 PowerMac.
If the Amiga community can't get its act together on hardware platforms, the rapid advance of platforms outside our community should provide enough power to emulate anything we run within our various camps.
So guys, I'm still focused on that X5000/40. After all, that will run MorphOS, OS4, and Linux.
But, once you all embrace low end hardware like the A1222 (which will only run OS4 and Linux, and then only moderately well), I will hopefully have better hardware, and will be working on a unified emulation of everything you have with a platform that can run that and more.
Good luck with the direction so many of you want to take.
The goal is to pedestrian for me.
