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).

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?)
