Well, anther question about the CMI accelerator. Hw does it work with genlocks? I am asking because I was under the impression that the 7.19 (or whatever) Mhz rate was important for NTSC compatability. I would like to use the board for animation work, especially to speed up and smooth playanim. So the switch to make it 7.19 to tape would defeat one of my major reasns for buying the board. Thanks for any replies. Ben Jacobs University of Pittsburgh

I have one in my machine, and have noticed a little speedup with animation playback. But, it's subtle, the playback speedup is more substantial with an '020'. So, if you're only reason for getting the board is to speedup animation playback, it might not be worth it. What it WILL give you is a substantial speedup when rendering the frames. Remember that the biggest speedup you'll find will be in math intensive opereations.

From article <12528@cisunx.UUCP:, by bdjst@cisunx.UUCP (Ratso): : Well, anther question about the CMI accelerator.

We use the systems existing 7.16Mhz clock to synthesize our 14.32Mhz signal for the processor and still allow everything else to use the standard clocks. Since the Genlocks don't have to worry about the processor speed, there's no incompatiblity there. (I believe that the genlocks usually use their own clock for the system also...) : Thanks for any replies. : : : Ben Jacobs : University of Pittsburgh -- -Bill Seymour ...tektronix!reed!percival!agora!billsey ...tektronix!sequent!blowpig!billsey Creative Microsystems Northwest Amiga Group At Home Sometimes (503) 684-9300 (503) 656-7393 BBS (503) 640-0842
