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.

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.)
