  My latest 1044 wiring has pins 1, 8 and V+ supply connected, pin 3 and battery- are Gnd.
  Pins 2 and 4 have a 10uf cap, the +side to pin 2.
  Pin 5 has the -side of a 10uf cap, the + side of that to ground, this is supposed to be the -9v pin.
  Battery measures 6.9v, and 6.8v when connected to the circuit, so I get 6.8+VDC @ pin 8, and -2.8VDC at pin 5.
  New, clean, simple board Has been looked over and double re-checked with DMM to prove all connections are made, no 'extra' connections are made...
  I thought I'd be able to see a ~evenly split supply...
  Edit: Prologue.
  Doesn't work with a bad chip.
  With a good chip I'm reading _8.8/Gnd./+8.8VDC, using a battery that reads 9v unloaded...or...perfect looking results.
