The base board is currently starting beta testing with customers and will ramp in production in the next two months if everything goes well.
We'll need to see if expansion board works as planned, but it shouldn't be too far behind.
Best,

I think Natami just ceased to become relevant....


Modern (fast memory) + a 100Mhz 060 would run OS 3.9 at a 'reasonable' speed I reckon.


If this comes off, even some (would-be) NG Amiga user's might change their mind ;)


I think you need to do more research.   This is not Natami's target level of performance.

Congrats to this project.  This will be the ultimate retro hardware (simu/emu)lator.
Since it's going to be capable of emulating all retro hardware, what is the incentive to upgrade it further in future revisions thereby negating any future price drops?  Also, the cost of this '060 board should be easier to pin down, are they known?  '060's are not cheap regardless if they are going on a Natami or a Replay board.

You can buy an 060 for about $40.

I have a 68060 MASK E41J on my desk here, so I hope that Yacube will put a socket on the board so I can drop in this sucker... :-)

It's my understanding that the higher-clocked ones can be pricey.  Where as 50Mhz ones are cheap(er).

Can somebody explain the performance difference between the 68060 and 68EC060 - the later lacking the MMU and FPU?

EC devices are much easier to get hold of. I am guessing when using an EC device the FPU and MMU (if required) are caught by the exception handler and implemented in software?

Strange from the link on freescale site
 
EC has both
 
LC has no FPU ???

Dont use EC or LC 68060 in Amiga system, it will cause crash because Setpatch and 680x0.library's depend on existing FPU and MMU.

I do have an 68EC060 here for testing, it leaks FPU and program like sysinfo just crash at MFLOPS test.
WhichAmiga says: MC68LC060... MMU: present (and in fact working) - FPU: not available (true).

AlexH "MC68060RC50, with the Mask 1E41J." are the ones to go for apparently..
Overclock and run cool.
I'll make some inquries in China next time I am there, they probably have buckets of them hidden away.

You'll probably find someone who will offer you 1000 of them and then some poor Chinese guy will spend a week unboxing brand new Amiga 4000Ts to yank the CPUs out of them.  :D

LC has MMU but no FPU. EC has no MMU or FPU.
