I forgot if there=E2=80=99s a space for thi= cker display with LED backlight... Yamaha dialect in the schematics: - Pin 4 is described as MA0 - but it is standard RS (Register Select) - Data pins 7 - 14 are described as PD - +5 V is pin 2 There are also mistakes: - Pin number under C1-4 should be C1-2, not C1-7 =20 - Pin number C1-8 is there two times, one is connected to the ground.=20 - There=E2=80=99s another pin without number connected to the ground=E2=80=A6= Daniel Forro > On Aug 30, 2018, at 10:46 PM, Brian Willoughby <xxxxxx@xxxxxxxxxxxx.xxx> w= rote: >=20 > He=E2=80=99ll need a very specific part number, even with those handy rese= llers online.
