Yeah......but look at the other Sharp models that guy sells.....9191, 9292, 9494, 666, etc......I can't see China bothering to replicate small-time boxes like that. Some of those weren't even very popular.
That guy sells mostly Sharp.....That's not just a coincidence. It's probably because Sharp had an assembly plant there. Think about it, it would have been impossible for Japan to manufacture AND assemble all the crap they claimed to make back then. Cars, toys, electronics, come on...... Not in such a small island nation that's smaller than California. I'm pretty sure they outsourced a lot of their production to other Asian nations without telling the consumer. Why not, who would have stopped them?
Either that or it was a warranty return center. Clean up the good ones, sell them to 2nd tier department stores, sell the rest to street vendors, or just lock them away in a warehouse if you can't figure out how to dispose of them.
