[Coco] Video adapters

[Chester A Patterson]

So, how'd it go running both adapters simultanously?

You can do that BUT  the input resistance of my converter is 50 ohms.
If Christopher's device also  has a low DC resistance (50-75 ohms) then
one or the other must increase it's  resistance to avoid overloading the
outputs in order to use them  simultaneously..
By the way Chris, if your converter  doesn't have a 50-75 ohm
input resistance on the RGB signal lines (not on the  sync lines)
then try applying this amount of parallel input resistance and  see
if the image improves.   The output circuits where designed to  drive
this type of load.
