I'm beginning to think if I get the resistor values correct, and also adjust the R, G, B settings on the tv (which it has) I may be able to get a pretty good picture...

So you DO need to solder in the resistors?

I think I might just have to annoy johnim into making me one.

I haven't seen the correct colours and brightness using the ypbpr input at all...
feeding the signal into anything...
even using variable resistors to try and "fine tune" it.

you're much better off using the header pins (rgb) on the GBS, which don't need resistors.
 
hi ubermick i never used any resistors, the cable is simple if you can use a soldering iron its 5 wires, you just need a 23pin socket and housing or a modified 25pin 1 and some wire sheaf i just reused a 25 pin serial cable took the old wire out and threaded new wire in.

exactly what i do

Oh right, now I'm getting it. So basically then, you're using the wiring harness that comes with the board, the one up top in this:

$(KGrHqR,!l!E-b3n7WVgBPz5TcJ)wQ~~60_57.JPG


And just soldering a 23 pin female to the unstripped ends of that, as outlined in that wiring diagram then? Easy peasy.

And if I'm right about power, I'll need a separate little adapter, since a bog standard A1200 won't provide enough juice (5V 2A) to power this with any sort of stability?
 
John, you're a gentleman and a scholar!
He's also magic!!!
No, it's true!
I was having trouble with my 8200, and was losing hope!!
(I can be melodramatic around hardware.. That's why I'm a software guy..)

John stepped in and told me it should work (cabled right, etc), and to try it again..

I did, and it worked....

Magically...

Been working ever since..

;-)

desiv
(p.s. Yes, it's "possible" that I didn't actually push the right button with the correct wiring at the right time.. But I prefer to believe the magic angle...)
 
Erm, I'm sure John's a lovely bloke. :whistle:

I just hope this wee box will magically make a PAL Amiga work on a Dell monitor here in the States. If not, I've had a poor Amibayer swap out a mainboard in the A1200 I'm buying for nothing!

it will work with any pal and ntsc amiga(all screenmodes) on any vga compliant display:)
 
desiv i wish i was magic

as roy said i will work on any amiga as there all the same other than voltage changes but thats not needed for the rgb cable and with any monitor as i have used on a few

Right John, sorry to keep pestering you about this, but seems I'm dim as a bulb these days. It just showed up, and am going to solder together the cable to take this to the A1200 (even though the A1200 isn't here yet... bloody post)

Unit came with two leads. One's a six wire that forms the basis of the cable, and connects into the wee harness behind the VGA port, next to the RGB input and pot switches. Second lead is a simple red and black power lead. I'm assuming this doesn't get used, unless I was powering this from an internal ATX power supply? So of the two leads, the only one I worry about is the main one, which is wired...

Red -> Pin 3
Green -> Pin 4
Blue -> Pin 5
Grey -> Pin 10
Black -> Pins 16, 17, 18, 19, 20
Yellow -> Pin 23

I'm ASSUMING that the yellow wire on the harness is the 5v power from the unit?

OR am I disregarding the yellow wire, hooking up that little power cable, and connecting the red from THAT to pin 23, and connecting the ground... somewhere else?

all ok will work fine

but dont use yellow not used its h sync

or connect anything to 23 its power
 
So I don't need to connect anything to pin 23? Pin 23 is carrying +5 coming from the Amiga, just not enough amperage to power the unit?

So just wire 3,4,5 (RGB) 10 (grey sync) and 16-20 (black ground), disregard the two wire power lead, and run the power from an external wall adapter jobbie?
