I've got a SC board in my hands which uses a National MM5837. From the
National 1977 Audio Handbook: The MM5837 Digital noise source is a MOS/MSI
pseudo-random sequence generator, designed to produce a broadband white
noise signal for audio applications. Unlike traditional semiconductor
junction noise sources, The MM5837 provides very uniform noise quality
and output amplitude. [yada, yada, yada] The output of the MM5837 is
broadband white noise.
