well i already have a 24bit dac and the video encoder chip. this will get me composite and s-video out.
Anyone have an idea of how to clock all these chips? my ad723 requires 3.58mhz (NTSC frame burst) so the z80s will run at 6 times that for 21.48 and the ARM chip is 50mhz so 14 times 3.58mhz will get me 50.12mhz. I hear these shift registers top out at 25mhz which is perfect.
