TK-90X

TK-90X

(computer)A Brazilian clone, manufactured by Micro Digital, of the British Sinclair Research ZX Spectrum8-bit microcomputer. It differed from the standardSpectrum by adding an Interface 2-compatible joystickinterface, and extra BASIC commands to aid programmingand graphics-editing. Because of these differences, it wasslightly incompatible with the standard Spectrum.

A later model, the TK-95, which boasted an improved keyboard(similar to the Commodore 64's) and a more compatible ROM,was little more than a Timex TC2048 (another Spectrumclone) in disguise.
