@eri the import ban produced several unlicensed clones, such as gradiente's phantom system (NES), microdigital's TK series (sinclair computers and apple II) etc
it wasn't prohibitively expensive, it was prohibited at all because the military dictatorship at the time (until 1985) wanted brazil to fend for itself and make its own electronics rather than import them (it didn't work)
@eri source: i'm from brazil, so i already know this whole story
