Mc68060fe133 ?

According to the Freescale (aka Motorola) website they never manufactured an MC68060FE133

Hmmm, Freescale don't list any FE parts on their website. Even in the obsolete section.

Except the XC68LC060FE50 and we know they made others... so not a good resource of information

Seems very strange to me that there would be Motorola branded parts dated 2008 when they had spun off their chip division as Freescale many years earlier and all chip lines had been re-branded Freescale.

The picture of the NatAmi chip has the mask G59Y which is a special low cost mask just for EC/LC cpu (i.e. it physically has no FPU) and is not the latest Rev6 mask set so it has at least one bug.

They would lack MMU and FPU functions, but conversely they would operate at a fairly high speed. I could see using these in a low cost Amiga accelerator.

For me, an EC060 would be of no use to me for a classic Amiga accelerator. The 060 code I want to run expects an FPU. Few 060 AGA demos would run. I guess if you didn't care and just wanted a faster 680x0 base unit then maybe.

The lack of an embedded MMU and FPU is not AFAIK a sign they would operate at higher speed?

It could be a valid "Motorola" part number that was produced before Motorola was taken over by Freescale, couldn't it?

With a manufacture code of 2008? The answer is no.

I am still not convinced that this part is not a legit 133MHz part from Motorola

The product code "MC68060FExxx" isn't enough to pursuade you? With a G59Y mask it has to be either an MC68EC060FExx or MC68LC060FExx.

I've never heard of Freescale or Motorola ever get this wrong.
