Interesting reply from Freescale Germany:
I can't find the Freescale document referenced that post.
I don't automatically discount Freescale Germany, as the German subsidiaries of US companies are usually very competent (I was particularly found of AMD's Dresden manufacturing operation until it was transferred to Global Foundries).
But we seem to have a difference of opinion here.
One from the parent company, and another from an off shore branch.
AND the MC68060FE133 is only available from Chinese source.
That alone makes it questionable.
The Chinese have a history of counterfeiting, and why aren't there any 'FE133s found elsewhere?
Also, from tests we have seen that the 'FE133 does not like to run at 133MHz.
Personally, I hope the community's efforts at creating a good FPGA 68K core will progress to an ASIC.
That could run much faster than 133MHZ.
