TK-90X (computer) A Brazilian clone, manufactured by Micro Digital, of the British Sinclair Research ZX Spectrum 8-bit microcomputer. It differed from the standard Spectrum by adding an Interface 2-compatible joystick interface, and extra BASIC commands to aid programming and graphics-editing. Because of these differences, it was slightly 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 Spectrum clone) in disguise. comp.sys.sinclair FAQ.
