The explanation from a local Apple rep was that the built-in video is actually faster in 1-bit mode than using a NuBus video adaptor. The two are about equivelant in 4-clolr mode, and the NuBus card wins in 8-bit mode. Of course, 32-bit color requires an external adaptor. >(b) Isn't the resulting system memory (1Mb - 640*480 bytes) >pathetically small? >So doesn't that mean you must buy 2Mb of memory to use the built-in >video? This one is strange. What are you refering to? The system memory in the IIci is not limited to 1 meg - the system I saw was 4MB & going strong. It can be expanded to greater RAM amounts, of course. As an aside, the ROM is 32-bit clean (says Apple.) -- Bill Douglass, TCADA "I dreamed I was to take a test, in a Dairy Queen, on another planet." L. Anderson
