Buy a 20x2 LCD alphanumeric display with 8 bit controller interface
and connect it as described below to your LPT1 port.
LPT pin: LCD pin:
GND 1 (GND)
Use external 5V 2 (+5V)
GND 3 (GND Contrast should be connected to variable resistor, but this works for me!)
17 4 Register select
GND 5 Read/Write
1 6 Enable
2 7 (D0)
3 8 (D1)
4 9 (D2)
5 10 (D3)
6 11 (D4)
7 12 (D5)
8 13 (D6)
9 14 (D7)
Use external 5V 15 (LED backlight anode +) Don't forget to limit the current
trough the LED as it might get damaged otherwise.
(Most backlight LEDs require a 5 Ohm resistor.)
GND 16 (LED backlight cathode -)
Have a nice day
