I think that what he means is to have like TWO machines in inside
ONE cube.  The 030 board can then be connected by "network" to the
040 board.  Since the 030 board lacks the ability to use the bus
(The missing CHIP ...)  Then there will be no BUS confilcts.  
The 030 board can then have a SCSI drive attached.

This is NOT the same as having a machine with multiple processors
and that use the same bus, etc.  This is like having TWO cubes
connected by a ethernet cable (in this case the two cubes share the
same casing).

The main problem is to boot up both boards when you press the power
key and then to be able to shut them down.  There should be a way of
doing it.  The power supply should handle both boards (maybe not two
monitors ...).

Any sugestions?
