Prológica Indústria e Comércio de Microcomputadores

Founded in 1976, the company initially commercialized machines for accounting use, namely the MCA-100 and Alpha Disk. The first models had an Intel 8080 processor, and in the early months the company even managed to get a partnership with Olivetti.^[5]

The company later specialized in producing products similar to the American TRS-80 series of microcomputers, under the general name of "CP" (for "Computador Pessoal" in Portuguese, "Personal Computer" in English).^[6][7]

One of its biggest successes in the professional field was the CP 500, compatible with the TRS-80 Model III.^[4][5]

In 1990, the company was sued by Microsoft for creating SO16 ("Sistema Operativo 16"), an operating system based on MS-DOS.^[8][9]
