Note:
Any cables connected to the CommPlete 4000 should be shielded to reduce interference.
Note that the two top expansion slots share a data interrupt signal on the PCI bus.
Consequently, if both slots are used, they must be occupied with identical devices (and the
device drivers must be identical). This is a constraint of PCI bus architecture. Also, the device
drivers must support interrupt-sharing. The drivers for the MultiTech ISI card do support
interrupt-sharing
