TK-90X definition computer
A Brazilian clone
, manufactured by Micro Digital, of the British Sinclair Research ZX Spectrum
. It differed from the standard Spectrum by adding an Interface 2-compatible joystick interface
, and extra BASIC
commands to aid programming
-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.
