Prológica Indústria e Comércio de Microcomputadores

Prológica Indústria e Comércio de Microcomputadores, commonly shortened to Prológica, was an influential Brazilian microcomputer company that reached its peak in the mid-1980s, when it ranked third among national companies in the sector.

History
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.

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).

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

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