[Coco] PICs and S-Video

Well, the S-Video converter works well and is centered enough on the LCD
TV, but off a little to the left on the Big TV, because of the late HSYNC.

    I'm working on delaying it (by almost a whole line), but, the TTL is
getting pretty complicated. It was suggested that I use a small PIC, but,
I've never used them before and don't have a programmer. Seems pretty
brain-dead. One input, one output and a comaparator/analog input. Take an
interupt on HSYNC, start a countdown timer (value based on the pot
connected to the comparator/analog input), take an interrupt on time-out
and output the HSYNC pulse then. 

Suggestions, input, offers to help???

in the mad rush to upgrade systems to do things that aren't needed by
people who don't understand what they are really supposed to do with them.
