Clever tricks are always availible to help: A 320x200x24 screen is 192k In one refresh frame the Amiga can send about 100k, and in 60 frames this is the 5.5 megabytes figure we recognize. The Colorburst has 1.5mb of onboard memory, this is enough to store 8 lores 24bit screens. Also, the Colorburst apparently allows selectable bit-plane depth with full 24-bit color look-up. So you could conceivably use 8, 10, 12, or 16 bits per pixel for 256, 1024, 4096, and 65536 colors respectively out of 16.7 million (this assumption is based on what little information I have on the board). I would expect 4096 colors from a palette of 16.7 million to look quite good. Does anyone know if the Colorburst will come with software that will allow a series of 24-bit pictures to be converted into some kind of special anim file that takes advantage of all these ColorBurst specific tricks? I also get the impression that the Colorburst is somewhat programmable. Would it be possible to program it to support special HAM-like modes for extended colors with fewer bitplanes (ala HAM-E)? It does sound like a very exciting product. I was ready to buy DCTV or HAM-E, but now I am prepared to wait until I can at least see the Colorburst in action.
