What kind of data could the CoCo *receive* from the Chip? Is there kind 
of a handshake (like XON/XOFF)? Could the chip report its settings to 
the CoCo?

I was always planning to make an AL design which fits exaxtly in this 
spare place of the CoCo3's bottom and connects directly using an Flat 
Ribbon IDC 10-Contact Socket Connector and a *very* short cable (if 
necessary at all, I don't know if there's a conector which could be 
soldered directly to the adaptor's PCB) to optimize picture quality.
