I am looking for a replacement for an MSV1 Board to support the Synchronous V24 connections to Hicom 300's from the Manager server. It is a version 3.0 Manager on the Unix Platform. The card will be a PCI type card(I think!). I have found a part number L30280-G600-A650 and I am also looking for the manufacturer of these boards also. Has anyone com across these or knows of a compatible equivalent or a second hand replacement. The new ones are extremely expensive!!
