Is there any sort of product tree document for Honeywell anywhere online? Honestly even though I was a Systems Analyst on a DPS-8, and have worked a little with DPS-6’s, they have an incredibly confusing list of names. :-) The FNP I’m most familiar with is the Datanet-8.

It looks like you need a copy of Multics Communications Software (MCS). Have you seen the following document? It appears to touch on some of your questions. http://www.bitsavers.org/pdf/datapro/communications_processors/C13-480_Honeywell_DATANET_6661.pdf I think we were using GRTS on GCOS-8, as I remember that name. It looks like you’d need a copy of the firmware, and a copy of the 8” floppy with system test and diagnostics programs. I’ve been trying to remember if we had to do any sort of software load on a Datanet-8, and I can’t remember needing to do anything like that. Though obviously the Datanet-8 is newer than a Datanet-6661. Zane
