Although it was produced in limited quantity for a few months only, the Atari 1200XL is common in the USA. Still, it remains much more difficult to acquire for European collectors like me.
Nowadays, I am still amazed by the timeless modern look of the XL series. An Atari XL (800XL) was recently included in a French auction of 2.000 objects with iconic design, ranging from Dieter RAMS (for Braun) to Le Corbusier (who was credited for a radio).
I am very lucky – for a European Atari collector – to own several 1200XL, including a early model made in the USA and a later model made in Taiwan.
