[QuadList] Another Jeporady Question

[Ted Langdell]

Hi, Trevor,

The question was "What other manufactures built quad machine?"

Bosch certainly built them.

They did so using patent licenses from RCA—and by extension from  
Ampex, which had cross-licensed patents with RCA.

Ampex limited the number of machines Bosch could build according to  
the on-line sources I'm aware of.
