I have a '030 Cube board here. On that board, you have everything from CPU, sound, SCSI, network to bw graphics.

The only NeXTbus card that was made public was the NeXTdimension that made the cube color. With such a card, you could run multi-head (one bw monitor and one color on each NeXTdimension card).
So there is nothing like SMP. You have 2 computers in one box.
