The '''TK90X''' was the first [[Brazil]]ian ZX Spectrum clone. It was launched in 1985 by [[Microdigital Eletronica]], a company located in [[São Paulo]], Brazil, which had previously manufactured [[Sinclair ZX81|ZX81]] clones (TK82, [[TK82C]], TK83, and [[TK85]]) and a [[Sinclair ZX80|ZX80]] clone (TK80). The ROM was hacked to include a UDG editor, and accented characters. In spite of this, incompatibility issues with ZX Spectrum software are very rare. The keyboard membrane is more durable than that found on the original ZX Spectrum 48K. The TK90X also features a Sinclair-compatible joystick port.
