A Microdigital Eletrônica Ltda foi uma das empresas pioneiras no mercado de microcomputadores no Brasil, tendo grande importância na popularização da informática durante a década de 1980. Fundada em 1979, a empresa se destacou por criar e distribuir uma série de microcomputadores compatíveis com modelos internacionais. A Microdigital se beneficiou da reserva de mercado imposta pelo governo brasileiro, o que levou a empresa a desenvolver produtos que atendessem à demanda interna por tecnologia, educação e entretenimento.
