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.
