  The MM5837.  A 17-stage feedback shift register.  Cute little device.  I
made a better one a few years ago, though: a 12C508 (8-pin) PIC program
for a 32-bit feedback shift register.  It included a little delay routine
to alter to noise spectrum.  Hm, with a 12C672, I could put a control
voltage in to set the noise clock rate..heh heh
