This collection of historical documents centers on the Atari 7800 and its hardware, with many originating from the late Atari historian Curt Vendel. Some materials were publicly available through his Atari Museum website, while others have been preserved from his private archives and are now being shared more widely. In no particular order...
A five page document outlining Maria's technical specs and architecture. The purpose for this document appears to be a high level introduction of the Maria chip to customers. Note 1: page 1 mentions a version of Maria with number 1722 intended for 680X0 series processors. Note 2: page 5 describes the CTRL register's test/forbidden DMA mode as "Does not assert HALT", which doesn't appear to be documented elsewhere.

The Subsystem Top-Level Specification for the planned "Minnie" in-cart soundchip. See The 7800 Minnie sound chip page for more information.
The analog Output Section Specification for the planned "Minnie" in-cart soundchip. See The 7800 Minnie sound chip page for more information.
