There are two NuBus cards that have problems fitting in a Macintosh IIcx.
Both are video cards: the SuperMac Spectrum 8-bit color card and
Truevision NuVista 24-bit color card. Apple has been unable to verify
whether or not the DCA MacIrma card fits properly in the Macintosh IIcx.
We will try to provide more information as it becomes available.
Note: Any NuBus card designed to the physical specifications published by
Apple will fit properly in a Macintosh IIcx.
