I thought so too, but it could also be software emulation...

OTOH, in the Commodore scene, there are lots of replica chips available these days so that you can build a complete C64 from scratch using the original Motherboard (and even on the Amiga some of the rarer chips are being re-created, like the Agnus)

Of course, that's not much different than using an FPGA to just emulate everything, but the one-chip-at-a-time approach has the advantage that you can swap in original chips that you might find, and only replace those that you're missing...
