[cctalk] CTOS Ethernet EDL software

There is a copy of the Convergent CTOS EDL (ethernet data link / packet driver) for the ETH150 (SMC 8416T ISA ethernet) board on Bitsavers. I am wanting to make use of an SG410P (CTOS EISA Ethernet IOP) but as far as I can tell the EDL archived on Bitsavers is missing the piece(s) necessary for use with an IOP or other supported non-ISA ethernet board. Has another copy of the EDL survived? Can it be made available? It might be the case that it was included as a separate disk in another CTOS networking software package (e.g. TCP/IP, OSI Transport, or LANce). Secondarily, CTOS FTP has ISAM II as a pre-req; Bitsavers has (what appears to be) an update-only disk archived, but no “base” install. I’d be quite interested in finding out if that has survived and could be made available as well. If there’s a more likely mailing list or forum I might also direct my enquiries, I’ll be glad to engage there. Thanks! ok bear.
