The term "digital RGB" is not in common use. The modern DVI (aka DVGA)
interface does separate the RGB signals into separate digitally encoded

Apple //c could not have implemented it.
RGB is sending the color signals on separate wires, right?
"Digital RGB" is when only a logic level rather than voltages are
interpreted on the R, G and B lines. IBM's "CGA" and later "EGA"
standards (way before 1999) were "Digital RGB", but the VGA (later) was
analog RGB.
Apple 2 GS also has an RGB output in addition to composite NTSC.
