"Unusual" would be a recent acquisition of an Apple II Rev 3 motherboard that has no solder mask or graphics. Not sure if it's a prototype or an impeccable 1 to 1 clone and I'm not sure I will ever have confirmation. This board was produced on the same material by the same manufacturer of Apple II boards of the time but has a couple of replaced interface card slots and is actually roughly cut on both ends. The card slot replacements could have been because of a lot of testing with various cards (a theory). Still remains a mystery but I am leaning towards prototype.
