We don't have any Tangerine Systems. Yes you can plug 50 way ribbon cables into the fader mother boards. You probably need custom 50 way ribbon cables go from the fader mother boards to the interface. There are one to one. Normally they are already in the console, that go to the connector panel under the patchbay. If you want Recall, you would need a recall card per channel and the main driver board. I'm not sure where the driver 20 way ribbon cable goes, since there is no recall computer. I assume the interface box, like the fader ribbon cables.
