      Double check your chip orientation (position)
      Hit each connecton one more time with the soldering iron just to make sure you got good connections.
      Did you happen to overheat the chip while soldering it? (seems unlikely but possible)
      Sorry to hear you are having trouble freeforming.
      That's my personal favorite technique.

      well needness to say the SPSH i built works well...i get about 10 to 15
      degress of rotation per shot but now the disappointment....yet again i've
      freeformed the circuit modeled directly from the breadboard and the thing
      dont work right.... i get tiny twitches.
      I've compared every connection to the breadboard version at least 8 times
      and there are no mistakes and no shorts all components are the same value as
      the breadboard.

      i dont want to add this one to the pile of about 15 other freeformed
      circuits i've built that dont work...come to think of it every freeform i've
      done has failed to work properly or at all
