|

This is a 10Mb hard-drive. With up to 8 multiplexers with 8 ports each it's possible to connect up to 64 Atari 800's up to a single 10 or even 20 megabyte Atari system. Still in use Today at the Fordham Prepatory School in the Bronx, NY is a 64 Atari 800 computer network hooked up to a single Corvus Hard drive system !
|
||
|
||
The Corvus hard disk system also sported a unique and innovative back-up system called "The Corvus Mirror" which was a VCR interface system that allowed you to plug a standard Video Cassette Recorder (VCR) up to the Corvus Hard Drive System to save back-ups of the hard disk onto actual Video Tapes!!!

The Atari 1400 XL has the same characteristics as the [Atari 800/600 XL](/museum/atari-600-800-xl/) machines exept for some new features: a new custom chip called "FREDDY" which replaces the old discrete semiconductors & TTL chips of the 600/800 XL to manage the memory. 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/).
