To me the only real Amiga is my Amiga 500. It has the original chip set and original code in, done by original Amiga engineers.
That would be the Amiga 1000 (or just "Amiga" as the first were called), the A500 was a cost reduced version by commodore.
What if Paula had been upgraded for AGA?
It wouldn't matter. Whatever commodore designed for AGA would have become an AGA Amiga. AAA was also an Amiga, albeit unfinished.
The Amiga Technlogies machines were also Amiga's, they were basically the same as the commodore machines.
There are no Amiga's produced since then.
You can't make an Amiga, in the same way you can't make a Ford Fusion.
