A 34010 GSP does the drawing. A DMA interface, just like the fancy new "bus mastering" IBM XGA. TIGA software interface. Which leads me to: >Id really like to know if it can be used with workbench, "legal" software, >etc. The A2410 "ULowell" card will not work with Workbench, with Intuition, with any existing Amiga software which uses any of the existing software libraries for their graphics. The A2410 uses a TIGA interface, which is a software interface standard designed by Texas Instruments. Many things are different from the Amiga's custom chip graphics: images are in "chunky pixels" (all bits of a pixel are adjacent in the same memory word) rather than bit planes; the graphics memory is not directly addressable by the 68K CPU; there's no Copper, etc. In short, any program that uses this card must know exactly what it's dealing with. So what in the world is it good for? It's main purpose is to give the Unix Amiga a megapixel color display for X Windows. You can't be a workstation without one. This card may never serve any purpose for most AmigaDOS'ers. -- First comes the logo: C H E C K P O I N T T E C H N O L O G I E S / / \\ / / Then, the disclaimer: All expressed opinions are, indeed, opinions. \ / o Now for the witty part: I'm pink, therefore, I'm spam! \/
