I have an image from a "MC68030RC50C" that someone sent me. It isn't suspiciously cheap but I'm not sure. Output from whichamiga isn't available. Does the following "(MMU NOT ENABLED)" indicate that this is a fake 68030? I'm thinking possible 68EC030 if no MMU.

The CPU isn't suspiciously new or anything, looks like it could be real. No real reason to doubt other than so many stories about fake CPUs around.
