I have the same LCD with the same circumstances but from my probing I found that:pin 1~ GNDpin 16&17~ V- for the back lightpin18~ NC (pin space between back light +&-)pin~19&20~ V+ for back lightI have a seeking suspicion that pin 2 is the LCD power and that the other pins follow a standard LCD module pin-out
Pin 1&2 are ground Pin 19&20 are Vcc, 5 to 27v Pin 3to10 should go strait to the chip, a binary counter should tell you what they do. Pin 11to18 should be functions. I could tell you more with a better PIC.

if i do remember correctly i took it out of an Old Credit car machine thing
That strongly suggests it was a one time special mass manufacture for thisone purpose only.We will probably never see its like in a future products again.
probably right easier to order one from adafruit
If it is a device that has to do with communication, look for the FCC # and then go here. http://transition.fcc.gov/oet/ea/fccid/help.html
the pc078pyl identity is the name of the chip and apparently there may be several manufacturers, check: http://core-ic.com/quote.php?lcount=2&S1=ON&P1=PC078PYL02 I think the 02 at the end is becuase it is now the 2nd version. I have no idea how to match a logo across a world full of corporate logos, but I did several searches for the pinouts based on that chip - all to no avail.
There are only a few mfgs of 20 pin LCDisplays. Is it feeding a Hitachi chip on the other side ? Or is it direct from the Taiwan black blob ? What will you do with the pinout once you have it ? A
Black blob i need pin out
Why is the manufacturer's name important to you? L
