SV-318

The SV-318 is the basic model of the Spectravideo range. It was fitted with a chiclet style keyboard, difficult to use, alongside which sat a combination cursor pad/joystick. This is a disc-shaped affair with a hole in the centre; put a red plastic 'stick' in the hole and it is a built-in joystick, remove the stick and it is a directional arrow pad for word processing etc. This machine also had only 16 KB of user RAM (plus an additional 16 KB of video RAM), which limited its usefulness, though this could be expanded via an external peripheral box.
