All this talk of C128s in 80 column mode has got me thinking about those
RGBI - RGB convertor circuits. There seems to be some variation between
different versions of the circuit, particularly with regard to resistor
values. Using the 1902 monitor RGBI circuit as the "definitive" reference
from Commodore, I tried to work out what a circuit for a direct SCART
connection would be. However, the 1902 circuit is a lot more complicated
than I expected; any idea what the node pulled high by R266 (2K2) is for?
