The TK90X, Microdigital's ZX Spectrum clone.

Microdigital Eletrônica Ltda. was an influential Brazilian computer company in the 1980s, based in São Paulo.


Established in 1981 by the brothers George and Tomas Kovari (whose initials were the TK of the domestic computers line made by the company), its first product was the TK80, a clone of the British microcomputer Sinclair ZX80.[1]

The company reached its height around 1985, with the launching of the TK90X (clone of the ZX Spectrum) and the TK-2000 II, a personal computer partially compatible (at Applesoft BASIC level) with the Apple II+. At this time, it had approximately 400 employees in three plants (two in São Paulo and one in the Zona Franca de Manaus) and more than 700 peddlers spread for all Brazil.[1]
