Yeah...the Unitron Mac512...it was built by a company called Unitron in Brazil, who made Apple II clones. Apparently up until 1992 it was illegal to import a computer into Brazil, meaning the computers there had to be "home grown". So Unitron decided they'd build a Mac clone, so that people in Brazil could buy Macs there. Anyway, since they used a copy of the Mac's ROM, Apple sued and won, and that was the end of that.
