then i'll write for others by myself..

just need a start.. thanks

the circuit seems simple enough and the code in C can also be written from scratch. All you need to know is how to control the parallel port.

u can see the Letter in the Comments

i will explain you in short how this Device work

let Write the b

u have that
Code: 
;b 
	db  7Fh	; 01111111
	db  44h	; 01000100
	db  44h	; 01000100
	db  44h	; 01000100
	db  38h	; 00111000
	db    0	;
u need to Seletect the First Columm using the 3 pins connected to 74ls164
then u send the 7Fh ; 01111111 in the Rows.
and Select the second Columm & send the 44h ; 01000100
etc etc

if you look like -> that
u can see a b


Code: 
 1111111
 1   1
 1   1
 1   1
  111


the Led need to Blink Very Quickly to seem On in the same Time
the pc can do that
but your soft need to stay in a Endless Loop to leave the Message on

to scrolle it
u need only to change from Colum 1 to 2 and 2 to 3 etc etc

Regard
i hope i helped you a little
 

i am very implressed of your assemply code;
i will try to translate it to c+ then post to you again,
wirhing you the best of luck
