This rather large and cumbersome box came out of the Atari corporate headquarters
in Sunnyvale, California. It was used in what Atari used to
call the "Shake & Bake" department. Quality Assurance engineers
would put Atari products through their paces to ensure that they meet FCC
standards and Atari standards for operation and performace.
This unit measured the audio/video signals from the Atari 800 Computer
System.
