MAKE YOUR OWN MULTI MODE/SYNC MONITOR TO VGA CARD ADAPTOR

LETS GET SERIOUS.....
THERE ARE A LOT OF YOU WITH MULTIMODE/SYNC TYPE MONITORS.
EGA IS NICE ,,BUT VGA IS GREAT !

CARDS ARE RESONABILE.......
AND AS THE COVER OF PC-MAG SAYS VGA..DON'T LIVE WITHOUT IT.

WHATS STOPIN' YA.............


BELOW ARE DIAGRAMS THAT SHOW MONITOR AND CARD PINOUTS
AND WILL ALLOW YOU TO BUILD A CHEAP ADAPTOR TO USE ON

(DON'T GET CONFUSED , SOME CARDS HAVE THE 15 PIN PLUG
AND THE 9 PIN AS WELL ... dON'T BE FOOLED IF YOU USE
THE 9 PIN JACK ,YOU STILL ONLY GET E.G.A. GO FOR THE 15 PIN)

TYPICAL VGA CARD PINOUT TYPICAL MULTISYNC TYPE MONITOR PINS



Now that we have some facts, lets look at an example:

(case in point..... Paradise vga card to Mag-multimode)


Working adapter cable..............

Plug to vga card Plug to monitor
1 --\ |--- GROUND ----------------- 1
2 -\ \ | 2 N/C
3 \ \ \------- | -- RED -------------------- 3
4 \ \-------- | -- GREEN ------------------ 4
5 \--------- | -- BLUE ------------------- 5
6 -------------| 6 N/C
7 7 N/C
8 --------------------- 8
9 | ---------------- 9
10 | |
11 | |
12 | |
13 -----HOR SNYC------ |
14 -----VER SNYC----------
15

15 WIRES DOWN TO SIX !! OH WELL WE NEEDED A NEW TYPE DB-PLUG !


ALMOST FORGOT........................... THE CONTROL BITS !

If you have a vga monitor forget the following.
(even if you don't you can usually forget them)

Their purpose is to tell the card what kind of vga
monitor you have. (color or b/w )

bit 0 pin 11 pin 11 grounded = color vga monitor
bit 1 pin 12 pin 12 grounded = b/w vga monitor

I found with the multimodes ... forget these pins.

I DO COMPUTER REPAIRS AND CONFIGURATIONS AS MY LIVING AND HAVE FOUND
THIS SETUP TO WORK ALMOST ALWAYS !!

Note: Please..... if you are not good at wireing or soldering, please
have a valid technician do this for you. (CARDS AIN'T CHEAP..RIGHT !)
