The TK83 followed the [TK82](/museum/microdigital-tk-82/). It was a close copy of the [ZX81](/museum/sinclair-zx-81/) but offered some enhanced features: 2 KB of RAM expandable up to 64 KB, and a joystick interface.

|
The tape speed could be either 300 or 4200 baud per second. The machine shipped with a beige or silver case, the same size as the ZX-81's.

Thanks to **Franco Girardi** for the picture.
