The DigiBoard supports daisy-chaining up to 16 concentrators off each of the two RS-422 ports on the back of the card. Each concentrator has 16 RJ-45 ports on it, which means you can have a maximum of 512 ports. Drivers are available for SCO Unix, SCO Xenix, and generic Unix System Vr3.2. Dunno if SysVr4.0 drivers are available; talk to DigiComm about it.
