Sounds like the original apple IIe RGB card (which were a V7 design) -
the round connector may have gone to a Kaga/Taxan style RGB display at
one point. A couple of pictures would help a lot here I think.
With a bit info, im sure we can figure out where that red cable needs
to go. These cards produce a good picture on modern LCD displays with
RGB style inputs, such as SCART.

I got it in an Apple IIE system I purchased of Ebay last week.
It has a jumper like header with a blue and red wire coming out that
clips on a couple of IC's I guess on the motherboard. Under the jumper
it says VIDEO-7 INC. There is a cable coming off of it leading to a 9-
D connector on the back.
I had to remove it after receiving because the Red wire lead was no
longer on anything and I have no idea where it was supposed to go. Not
that I have anything connected to the D9 connector anyways.
It did come with a very odd D9 to 8 ping connector that I've never
seen before. Looks almost industrial.
The search on the web had lots of stuff on the Amdek cards being
mostly for disk drives, but this may be different.
Any ideas??- Hide quoted text -

That sounds cool.
Right now I've got the Apple IIe connected through a cheap composite
to VGA converter to my Dell 17" LCD.
I must say the graphics loook great, but the text is really shifty and
hard to read.
It would be nice to find a cleaner way to get the video if possible.
Here is a picture of my card:http://rapidwave.net/amdek002.jpg
Any suggestions?
That "industrial" connector is the mate to the original RGB connector
on the back of the Amdek RGB monitor.

Ok, so I did some more searching on the internet given your
information and it appears in 1982-3 there was an AMDEK video solution
with a rather large card and a daughter card with an 8 pin output.
This card is much smaller, so maybe it's a newer generation?

Now what I need to know is if this card is all that is needed for RGB
output, and what monitor can I connect this special connector to?
Or is there another monitor I can connect directly to the D9 connector
from this card?

And where do the Blue and Red hooks hook onto the motherboard?

That 8 pin plug looks right for a Taxan/Kaga monitor (where Apple II should connect to the 8 pin connector rather than the DIN plug). I have two of these monitors that came with a BBC computer. The BBC computer uses the DIN connector. I don't have this plug so I haven't tried it on my IIe with the RGB card. Presently I use a CGA monitor with that machine.

That card looks simpler than my card, which is made by Apple. My card doesn't have the 10 pin header, only the 16 pin header, and only two switches in the dip-switch. The jumper puts 5V on one pin in the 16 pin header on my card. There is a 15pin flatcable that goes from the 16 pin header to a female 15 pin D type connector. (To use it with the CGA monitor I needed to regenerate a vsync and to invert the sync signals http://home.online.no/~kr-lund/A2E-CGA.htm ).
