A2080 i.e. Vampire 500 V2 on an Amiga 2000

It occurred to me that if you can provide 68k and "AGA" in an FPGA, wouldn't PowerPC also be possible?

I figured if a 100MHz 68k was possible, PowerPC wouldn't be too far-fetched.  

IBM even owns a FPGA implementation of PPC (of course asking for money). Gunnar says it makes no sense because it is too slow.

Oh well. Maybe this might be made some day:

It's for big box Amigas, though. I think Gideon is way too busy with the 1541 Ultimate right now though.  

Not really. You should keep in mind that the PPC has longer opcodes, and performs less operations per opcode as it is a risk processor. Thus, you first need twice the bandwidth of the 68K to get the same number of instructions into the processor, then you also need *more* instructions to get the same operation(s) done.  Thus, even if you get a FPGA implmentation of a PPC running at 250Mhz, you still don't have quite the power of a 250Mhz equivalent of a 68K. It's more like a 100Mhz 68K, if not even less.
