Here's a nice scan of the Atari page from the Christmas 1984 Argos catalogue. For our non-UK readers, Argos is a large High Street retailer who issue a catalogue twice a year. You order using numbers shown in the catalogue, and pick the goods up at a collection counter in the store. Argos generally sell a wide range of items, basically reflecting what's available at the time. Argos catalogues are designed to be thrown out when the new one is published, so finding an old one is very rare. It's interesting to note the prices at this point (late 1984), because just one year later Atari were dumping 800XLs with a 1010 recorder, joystick, and tape games for as little as Ł80 through Dixons/Currys (another chain of High Street electrical retailers).
