Title: 8200 VGA Board cable diagram
Post by: tribz on June 20, 2012, 06:20:47 PM
Does anyone have any cable diagrams for this?

I've got a 23-15 VGA adapter going into it but no picture. Composite working fine through albiet in black and white.

What I could do with is the wiring schematics for the 23pin video to the 8pin cable that it comes with or perhaps even to the 15pin VGA

I've seen the one on EAB with the ypbpr adaptor but dont want to try that one as it loses quite a bit of colour.

Thanks!

Unfortunately, the best info I know is on Amibay, which is down right now.. ;-(
I just built a cable for mine..

It's basically 5 wires (my 8200 came with a 6 wire header for RGB).
You need the RGB pins connected.
Then CSYNC (pin 10 on the 23pin I think) and ground..

Once you do that, you have to connect it, and then hold the DOWN button for several seconds.
That part was tricky for me.. I thought I did it, but it didn't work..

Trying it again worked, and it's been good since..

It's possible you have to select the proper mode first, and then hold DOWN.
There were a few things I tried, and that was one of them..

OK, just looked here:
http://old.pinouts.ru/Video/AmigaVideo_pinout.shtml

I used
Code: [Select]
Amiga                             8200
2                RED              RED
3                GREEN         GREEN
4                BLUE            BLUE
10              CSYNC          GREY
16              GND              BLACK

p.s.  ByteRyder beat me to the answer (I edited in my answers as he entered his)  ;-)
I didn't use Yellow.  In fact, I remove it from the header..

Thanks for that, I didnt know about the down button.

I've not got a manual with the card so can I assume on the 6 wire header cable that ...

R-Red
G-Green
B-Blue
Black-Ground
Yellow-Composite
Grey - CSYNC

Curse Amibays downtime, I was trying to get it through the google cache also!

Edit, thanks ByteRyder I'll try that now

Yeah, the down button threw me..  I thought I had tried it, but nothing.
Someone mentioned on Amibay to press it and you'll see a red LED on teh GBS start blinking..
I never saw that..
So I was trying it again, and I didn't think it was working...
Then, I noticed that the red LED was blinking...
A few seconds later, solid picture and it's been good since..  ;-)

Not sure if didn't hold it down long enough the first time or ???
It wasn't like I held down the button and while I was holding, it started blinking.
It was something after I let go...
