John: According to the hype they (sorry, forgot company name) uploaded onto several BBSs, the Chip Ram Accelerator would, er . . . do this: Most people beleive that their Hi-Res/16 color/Overscan animations play slowly because of the Delta Compression, (The difference between two frames that the computer must calculate.) and by buying the Fastest excellerator card on the market will improve their frame rates. If you allready have a 68030 this is not the case, animation speed is limited to the amount of memory you can move through CHIP RAM. for example, you can play a Overscan 6Bit plane Image (HAM/32 Colors) at 30fps, where as a complex Overscan 4Bit plane Image (HiRes/16 Colors) plays at 6fps. A good example of this is DCTV. When converting a 24Bit/Overscan animation to run under DCTV, you have a simple choice, make the animation either DCTV 24Bit non-overscan, or DCTV 64000 Colors Overscan. The Amiga 2000 family (A2000, A2500, Etc.) can move about 1.3MB of Imformation through Chip ram, resulting in frame sizes around 45K for best playback. With the A3000's 32Bit Buss, the speed increases to about 1.7MB/sec. Still your limited to about 50K a frame. The Hottest new product for the amiga will be shown on October 4th for the first time at the AmiEXPO in California. The CHIP RAM EXCELLERATOR! Over 5MB/sec of Information through Chip ram! Create DCTV 4Bit, Overscan, Animations that run in real time. Features: * A MINIMUM of 5MB (10MB-a maximum of 20MB) of Information through Chip Ram. * Adds 2MB of TRUE 32Bit memory to the A2x00. * Uses the A3000 Angus chip for maximum compatiblity. * Screen updates, Blitter operations will be increased.
