    What im looking at doing might not be possible. Basically im trying to produce a simple vga test signal (just a couple of coloured bars) using a 25.175 crystal and some TTL. Am I wasting my tme? I know a CPLD or FPGA would probably be better but hey - its a challange.

    VGA is simply a question of settings a few sync markers etc at the right times ;)

    Thanks for that. I realised that i was making this too complex in my design. A small alteration and ive knocked down the complexity alot by using a single 4bit counter as a clock divider. Ill post up my intended schematic in a day or so.
