TK-90X
TK-95

   <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.
