It has a speech synthesizer chip (Votrax SC-01) and a built-in modem (Bell 103 compatible, 300 baud). Thus it was conceived as an enhanced version of the Atari 600XL and 800XL computers and was to be software and hardware compatible with all the 8-bit Atari family systems. It seems that this computer was never marketed... All existing models are thus considered as prototypes. This system was also called by **Atari A1201**, **Atari 1200 XLD** and **Atari 1200 XLT**. Another model was announced at the same time : the [Atari 1450 XLD](/museum/atari-1450-xld/).
