QL Trackball is a fairly standard version of a trackball (also called the Command Control), produced by Wico Corporation and initially aimed at Atari home video games, then making it onto Commodore Vic-20,Apple II and TRS-80 home computers.
</p>
<p>
A trackball is almost like an upside down mouse, where you move the ball around with your fingers in order to control the joystick or cursor on screen.
</p>
<p>
This appears to have only been released in the US market - it has a standard Atari style joystick connector (OK for US and European QLs), but which would need a joystick convertor on the UK standard QL.
</p>
<p>
The unit is also powered with a 6V power supply.
