Who said he has to use one FPGA?

I'll wait and see, but the more I/O you have the more expensive the FPGA.

Just count the I/O required for:

PCI-32 (72-pins)
68k (88 pins)
SDRAM (116 pins)
Floppy disk (16 pins)
IDE (33 pins)
VGA (25 pins)
2x Joystick (14 pins)
PS/2 Keyboard + Mouse (4 pins)
16-bit Audio (In and out)
Svideo in and out

At over 400 user I/O you're looking at a single FPGA where the chip costs around the $300 mark. That's not even considering routing congestion, capacity etc.

Those are "Military" prices. End user prices are more the €80 mark. I just bought 3.

Because you'll never be able to "emulate 68k" at the physical level any time soon.
