Hi, all... A Blitter is a bitmap copying and transformation chip? Is this all that it does? Which chip is responsible for the STe's hardware scrolling? Most other game systems use a very fast graphics chip to take care of the sprites, scaling, scrolling, etc. My question is: If ATARI is interested in making this system a competitor in the computer entertainment market, why didn't Atari include one? The SNES has a CPU speed of 3.58 MHz! Everyone looked at this speed and laughed, but the graphics chip showed that the speed of the processor did not matter too much at all. The Sega Genesis is based on a 68000 CPU at the speed of 7.6 MHz. This system pretty much relies on the programmer for rotation, etc. BUT I'm pretty sure it still has a graphics chip. And I'm POSITIVE that the Sega CD-ROM player has an especially designed graphics chip for rotation. Recently, Nintendo announced to the world that it has developed a graphics chip that will be powerful enough for 3-D imaging. If the Falcon030 does NOT have a graphics chip that is responsible for these features, won't the video game systems pass this system by? Also, if the JAGUAR has a 64-bit RISC graphics chip like we all suppose that it will, the Falcon030 will NOT be able to run any of those games. I don't know. If I was Atari, I'd try to get the Falcon030 and Jaguar to both have the same graphics chip. This way game developers would be more willing to make games for these systems. And Atari would have an edge over systems. And wouldn't a graphics chip capable of helping out with all of these features save on memory? And programmers' time? I doubt there is any way that a FUTURE 64-bit RISC graphics chip can be added to the Falcon030 at another time... --
