MM5837?

[Harry Bissell]

This would probably work fine. The repeat rate is from 1.1 to 2.4 seconds,
there is
a large variation in clock frequency...  Sort of if you take two chips at
RANDOM...

Features:
* Uniform (ly bad) noise quality
* Uniform noise amplitude (yeah, a "1" or a "0")
* Eliminates Noise Preamps (true...)
* Self contained Oscillator (true)
* Single component insertion (true... you will just WISH you had inserted
more....)

BTW:  What features do they usually "claim" for BBD chips ?   ;^)
(teehee!)

OTOH... the MM5837 is long long dead.
