In Brazil, due to protective market regulations foreign technology companies could not exist, so a Brazilian businessman named Mathias Machline obtained in 1965 authorisation for using the Sharp brand in Brazil. Sharp Japan did not have any relationship with the Brazilian company, which used the Sharp brand from 1965 until 2002.

In 1985, the Brazilian Sharp company started to make MSX computers and peripherals. Although they launched the first MSX model on the market the Sharp HB-8000, and even if it strictly followed MSX standards, they did not win the market share they hoped for and stopped production in 1988. There were some rumours that the Japanese Sharp Corporation was behind the production stop, but this was never confirmed.

The Epcom brand was a whole owned subsidiary of the Brazilian Sharp, apparently created only to get tax benefits for this segment and only had minor appearances on marketing material, as everything was clearly labelled as a Sharp product. Nevertheless, it was responsible for the software, including the Hotbit BIOS. The Sharp brand on the other hand, was used for everything related to hardware. More information on this link.
