To avoid a long and potentially off topic discussion I suggest you check wikipedia for differences between 020 and 030, but short story is that the Vampire uses the Apollo core developed by the Phoenix / Apollo team lead by Gunnar von Boen.
The core is not a pure copy of a 020. It is in fact a new and improved 68xxx core even better than 060 in some respects but keeping it compatible with 020... it currently lacks FPU, not sure about the status of the MMU.
But as a simplification it is fair to see the core as something like a 250MHz 68020 even though it really isnt.
The team thats working on the FPGA Arcade (google it) are much closer to what you could call a pure 020 core.
Short answer is that there are some uses for both.
Stuff like Shapeshifter Mac emulator requires MMU (if I remember right), games like Quake use the FPU along with 3d rendering software (Although, who would render on Amigas these days) and some demos.
As for FPU, for compatibility reasons you can emulate the FPU on CPU.
I dont know all the details but its already done on Amigas. The FPUs on 040 and 060 are simplified compared to 68882. So instructions not supported in hardware are intercepted and emulated in software. I suppose Phoenix could do the same...
I know, right?I'd like to see AAA implemented in an A600, or at least in an A1200, that would be wacky![]()
