I received it today, take more detailed photo, let's read it clearly. Previously i posted a thread for discussion it's fake or not. I can feel her when touching her. In fact i was moved by it's beauty at first sight.
Now I dont think it's fake . and YOU? my dear friends

It is possible
the production code on the back was used by mostly DX-40's though

Lets think about this. I am assuming that with regard to fake we are refering to an old fake designed to fool the consumer not a new one desigened to fool the collector. I have yet to see a professional looking modern fake designed to fool the collector. I do not think a sufficient market exists to attract the kind of money a quality forgery would require. These old fakes were typically Chinese in origin, were mass manufactured, and are pretty professional looking. So, it could be a DX33 or something that has new DX50 text professionally added. On first glance it would be indestinguishable from a genuine should one exist. Soooo, plug it in and find out. It is unlikely that any internal modifications converting it to a 50mhz would be easy enough to perform even for a professional operation and it has not been repackaged as is often done so that the modifications could be done externally. If it boots at 50mhz it is real if it fails but will boot at 33 or something else it is fake. I suspect it is real.

I think that a fake DX-50 should boot at 50MHz, because if not it would be considered not as fake cpu, but as a defective cpu from the consumer who bought it.
And would be returned to the shop. So, it will not be interesting for the fake makers...
