All 030 CPU boards were shipped without NBIC chips.  NBIC is needed
if you plug additional boards (like NeXTdimension) into the cube.
This is still true for all NeXT boards.
For some time, if you intended to build boards for NeXT, I heard
that NeXT gave you a pair of NBIC chips for free.  Now, you
can buy them if you need them.

This is essentially a non-issue, if you upgrade to 040 board
before you plug in another board into the  cube, because 040
upgrade board comes with NBIC chip on it.
