[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???
