Fw: simple schematics

[The Old Crow]

  Once again, PIC to the rescue...

  I used the 8-pin PIC12C508 to fashion an n-bit feedback shift register.
It can do up to around 21KHz.  The clock rate can be tweaked (see the asm
file in-line notes) for interesting effects.

  (I put one of these into my Prophet-5 in place of the MM5837 on a small
circuit board).
