Re: RGB card

There is a 3 pin jumper block on my card. It came with the two left
pins shorted. I assume this is used to select which header is used for
output. I'm not sure what the J1 connector is for (just below the work
AMDEK). Would it be for picking up the composite video from the Apple
IIe motherboard? Isn't that what the similar looking 2 pin connector
on the Apple motherboard is?

I tried plugging the card into my Apple IIe and thankfully, no magic
smoke escaped. Connecting the card to a CGA monitor gives me nothing
but a blank screen. The Apple composite video works as always.
For what it's worth, the RGB card I have here required three clip-lead connections to pick signals off the motherboard that were not available at the bus connector.
With the help of folks on the list, I was able to figure out where things went and eventually got a display out of it. The unit I have is definitely not an Amdek, though, and bears no real resemblence to the units pictured.
