This is not an A3000+, the first picture was one of two prototypes and probably the pic was stole from Haynie's pics he put on the web long ago.
I don't trust the specs he's listing because the other two pictures are definitely Amiga 2000/1500 motherboards..
This is one of those "I am not an expert" posts which probably means it's someone's way of trying to up the price of a not very worth it Amiga 2000 Motherboard which is probably non-functional from the look of the two pictures..
