I think he is referring to the fact that the memory for the screen is located in main memory (i.e. along with the system and app heaps). So with an 8-bit deep screen, plus a normal System (~400K) one is not going to be able to run many mainstream business-type apps or graphics programs( especially under Multifinder). > >As an aside, the ROM is 32-bit clean (says Apple.) > How did the guys at Apple do this? From what I remember, in the August MacTutor, there was an article mentioning the fact that the main problem in getting a 32-bit clean ROM were CDEFs which use the highest bit passed to the CDEF to signal something. How about wait states in the IIci? Are there any? (obviously there are if a cache card is going to help performance,right?) Johnny Lee t-jlee@microsoft.UUCP ...!uw-beaver!microsoft!t-jlee
