Could one use the old 68030 board in a cube, along with the new 68040
board, by

1.  Cutting its traces to the internal scsi bus, 

2.  Connecting its ethernet port to the 68040 board ethernet port with
    a piece of coax, and

3.  Treating it as a diskless workstation, booting off of the 68040
    board, which is connected to its own internal hard disk, etc.

You would gain two serial-ports, a dsp port, a scsi-1 bus interface
(to the external world), a second printer-port and a second dsp port,
plus a second, slower computer.

The main cost, it if would work, would be the ram.  But 16 sims would
probably only cost $800.00 and you get quite a lot for that cost.

The clear reason for putting the 68030 board back in the cube is that
the cube has the right power supply, space, and backplane.
