I'm trying to use the graphics demo. I'm using the professional development board that has 4 resistors going to an rca jack. "Tv" is a child object under the graphics demo, I found the pinout for the jack in the dat section, but i'm not having any luck with the display. How to use the demo is not clear to me, am I missing something? Also I do have the tv set to video 1, which is the jack i'm connected to.
the broadcast signal nibble is arranged as:
'' bit 3: aural subcarrier (sum 560-ohm resistor into network below)
'' bits 2..0: visual carrier (sum 270/560/1100-ohm resistors to form 75-ohm 1V signal)
