a picture is worth a thousand words, so here is what I am getting out of my iic (keeping in mind I am using a 20mhz digital storage scope from kenwood that defaults at a date of jan 1 1987)

Apple video is shorter than standard (longer front & back porches) because it is designed to be in the visible part of a TV screen, whereas broadcast video is normally overscanned (extends past the visible area on both sides).

Click to expand...

that I get and quite clearly can see the porches are 2-3x the normal time, their timing is not critical, but the short total time per line is throwing the "loose standard" out of whack for brand spankin new tv's (the II's output is loosing nearly 3ms every frame)

meanwhile my thoughts against the ntsc colorburst is to simply bypass it during its time, though some form of pass through dongle, giving better 80 col text, maybe... we will see how my half page idea works out
