They are incompatible parts. The schematic requires a 2x16 Alphanumeric LCD and what you have is a 128x64 Graphic LCD. The program inside the chip will not drive the graphic LCD.

Clueless on this project I am.  If the LCD is compatible you should be able to just use pin for pin.  Do you have a Diagram of your LCD pin outs ?

Regardless of the pin count, they are not compatible at all. Not even close.

One of them requires a dot driver inside the computer chip and the other sends text to the LCD. Two different types of LCD despite that they look alike.
