I don't know if Bell Labs changed the name of our chips
from BELLMAC-32A and BELLMAC-32B to WE 32000 and WE 32100
before or after National changed from NS 16... to NS 32... .
We did have somebody design our naming convention to be
expandable and so on, and since BTL has lots of spare
lawyers I assume several of them were consulted.

(free advertisement time)  The WE 32000 Microsystem is a 5-chip
or 6-chip module (chips are mounted on a mini-PC card with 214
pins).  There are two MBI (microbus interface) chips, two MBC (microbus
controller) chips, a CPU chip, and an optional MMU chip.  Without
MMU, the whole thing is called the WE 32001 Processor Module.
With MMU, it is the WE 32002 Processor Module with Memory Management
Unit.

The 3B-2/300 uses the WE 32002 (it uses our MMU chip).  The 3B-5
uses the WE 32001 (it uses a discrete MMU).

Our second generation VLSI consists of individual chips, not all
mounted on a module.  The WE 32100 CPU is the CPU (naturally),
and the MMU is the WE 32101.
