Osmo, I agree in what speechguy writes.
In our part of the world customers will never change their Octel/VMX 200 or 300, for any reason.
So they keep rolling the stable and solid (as a rock) mashines.
We have sold them since 1992, and out of approx. 160 customers, I only upgraded one fro REL 7.1.5 to S.2.0.2-2, because the customer wanted networking throgh LAN/WAN.
Best regards form the doktor
