    It had the following text file for pinout:

    GLIPIC BOARD Ver C and and Higher
    =================================
    The GL board 20 pin header has the following pinouts:
    PIN ----- PIC PIN ------------ KS0108 pin
    01---------- GND --------------- GND
    02-----------Vdd 5v--------------Vdd
    03---- wiper of 20k pot-----------Vo
    04-----------PORTC.1--------------D/I
    05---------- PORTC.2--------------R/W
    06-----------PORTC.0-------------- E
    07-----------PORTD.0--------------DB0
    08-----------PORTD.1--------------DB1
    09-----------PORTD.2--------------DB2
    10-----------PORTD.3--------------DB3
    11-----------PORTD.4--------------DB4
    12-----------PORTD.5--------------DB5
    13-----------PORTD.6--------------DB6
    14-----------PORTD.7--------------DB7
    15-----------PORTB.1--------------CS1
    16-----------PORTB.1--------------CS2
    17-----------PORTC.5-------------RESET
    18-------one end of 20k pot----- Vee(connects to Vo via the 20k pot)
    19-----------PORTE.1---Do not connect to KS0108 LCD*
    20-----------PORTE.2---Do not connect to KS0108 LCD*

    *If the LCD has a backlight LCD PINS 19 and 20 are used to power the backlight. Usually, for an LED backlight PIN19 is the A (anode) and PIN 20 is K (cathode). However, on some displays the order is reversed. Check LCD documentation before connecting power to them!
    If you have a 128x64 KS0108 LCD with the above pinouts, then you can test out the GL board by running the Windows app GLUTIL2.EXE.
    All the credit goes to the good people at Compsys.

    I had saved these files back in 2005 when I was starting on LCDs.
