The purpose of the 68060 board is to reverse engineer the CPU asfair?, so it really doesn't matter too much unless that's the purpose.
Hello, this is André from the Natami Team.
lou_dias and vidarh kinda have the right idea here. No, the 68060 CPU card has nothing to do with reverse engineering. But it is useful in many ways.
First and foremost, the N68050 core is developed on a separate system and is not integrated in the Natami FPGA yet. This makes it absolutely critical having a physical CPU to get things up and running at first.
Secondly, our softcore CPU does not come with a built in MMU, since that would slow down the entire CPU too much to be acceptable. A MMU might not be very important for a normal user of AmigaOS, but a developer might want to use a MMU for developing and debugging purposes. Likewise, if you want to experiment with other operating systems that demand a MMU, the 060 card is there.
Thirdly, it is good having a physical Motorola CPU for comparision of compatibility and performance, both between a Natami system and an Amiga classic and between Natami systems using different CPU:s.
Fourth(ly?), The 68060 card will not be disabled once the softcore CPU is done, but will theoretically be able to be used as a kind of accelerator for certain tasks, providing that software is written for it.
The first stand-alone Natami board design actually had a physical 68060 directly onboard. But this design was scrapped a few years ago when the softcore project started.
Sorry for hijacking the thread with a long answer
