Two data points.  First, the Deskstation rPC44 had almost exclusively
custom chips on it.  The few chips that weren't custom were either
logic glue or do not have datahseets readily available.

Second, chances are very good that the MP stuff is custom ICs.

I've heard from some people inside of NEC that the docs do not exist
in a form that can be handed out.  Basically, they don't know where
the paper is, so they can't release it because they don't knows whose
filing cabinet or machine they are on.
