It is hard to suggest how to connect without the data sheet. Do you have a data sheet with it? You can request a data sheet from the seller.

Anyways, it should drive by the KS0108 Graphics Controller, and my best guess is connecting it with standard pinout (caution: It could damage the gLCD if it is not right connection).

There sholud have a 20 pins connector. Search and download one of the gLCD with KS0108 data sheet. Locate pin ONE, pin TWO and PIN THREE on your LCD. Verify that pin ONE connected to VSS (GND), pin TWO connected to VDD (or +5V) and pin THREE is Vo (to drive the display). Also chk to see if it has LED backlight and it should connected to pin 19 (Anode) and pin 20 (Cathode), but sometimes they connected to two wires.

If you have pin ONE and TWO right, then more likely you can power the gLCD without burning it. The remain problem is how to write program and display on the LCD.

Data pins: Somes use Pin4-11, somes use pin7-14.
CS1: Somes use pin12, somes use pin15
CS2: Somes use pin13, somes use pin18
RESET: : Somes use pin14, somes use pin17
R/W: : Somes use pin15, somes use pin5
D/I: : Somes use pin16, somes use pin4
En: : Somes use pin17, somes use pin6

It is better to get a data sheet for it if you confuse.

Best luck,

Tom

He's not going to see anything without hooking up the HIGH VOLTAGE CFL tube as well. This is an old piggie that does not use LED backlighting.

If you zap yourself with the CFL supply, you'll not be worrying about the rest of the pins.

Throw it away as junk, like the last guy did, and buy an LED-backlit display for a few tens of dollars.

Thanks for ansver. I thing the best solution is "Throw it away as junk" and buy new one. Because high voltage is out of time and too much complicated.
