[cctalk] Basys - newsroom automation

All, If you haven't worked in the television/broadcast business, you probably won't remember Basys. It was a newsroom computer system (NRCS) written by Basys Inc. in the late 70s/early 80s, sold to ITN in London who maintained it for some years and then sold it to DEC, who then sold it to Avid. I'm beginning to get some interest from several people in building a Basys installation on emulated hardware. From what I know, it may have run on VAX, SCO UNIX and IRIX, as well as Linux when Avid bought it. But for my purposes, I'm looking to build a system which supports serial terminals, possibly via a device called a communications control unit (CCU). Having searched all the normal places, I've been unable to find any installation media, no matter how old. Avid's website has some older versions of iNEWS that run on Linux, but this is far too new and doesn't support serial terminals. Does anyone have any installation media, or any pointers to people who might be able to help? Peter
