ASM-1 and Tempcos

     Yes I forgot to include the LM311 power pins on my schematics! I 
     didn't show them for the other chips, so I left them off of the 311. 
     It's a habit of mine showing through.... the schematics are of the 
     style that I use as "notes to myself"... sorry! The LM311 has a 
     strange pinout compared to "normal" op-amps. Notice for example that 
     the (+) and (-) inputs on pins 2 and 3 are reversed from the standard 
     741-type pinout. Also, the output is on pin 7 rather than pin 6.
     
     So - just for reference purposes, here's the pinout used in this VCO:
     
     LM311
      Pin     Connection
     --------------------
     
     1         V-
     2         (+) input
     3         (-) input
     4         V-
     5         no connection
     6         no connection
     7         output
     8         V+
     
     Again sorry for the omission.

On a slightly different note, anybody building the ASm-1 type osc as a 
separate module please note that pins 1 and 4 on the 311 are 
connected together.  I don't think this is shown on Gene's original 
schematic.
