The issue with the original Iic panel is its rarity and delicacy.  What wold be nice is a way to build a modern version that everyone could get access to.   I use a 7 inch LCD TV/monitor but those aren't good for 80 columns.  If someone could convert the video connector port into VGA, much like the Video 7 Iic RGB converter....
