IBM-PC Parallel Printer Port to 
Hitachi LM018L LCD Module 
Here's an example Pascal program

N.B. C0, C1 & C3 are inverted - i.e. C0 = 1 will cause Parallel Port pin 1 to go LOW. 
If timing is non-critical (no need to check Busy Flag DB7) then the R/W line - Pin 5 - can be tied to Ground (LOW). 

C0 and C1 can be used as select-lines for up to 4 LCD Panels. 

You can use the Game Port as a source for 5v 

The pin-outs of the IBM-PC GamePort - use any +5v & GND pins
