[sdiy] converting white noise to pink noise

No, no, no...you need to punch sequence numbers on your cards so you can 
use the card sorter - a masterpiece of electromechanical design.

My horror story was the pdp-11 assembly language implementation of the 
unix utility sed that had to be read on a card reader that occasionally 
read *two* cards at a time.  Let's just say my deck was big enough to 
usually encounter this, and that the OR of two cards != reading the two 
cards in sequence.

ob-sdiy: I used a similar pdp-11 as the control processor for a 
primitive four voice polyphonic synth in 81/82. Not exactly portable - 
the processor and peripherals was racked and stood about 6' high.
