I'm thinking of trying to get something running via SIMH soon, but I can't promise anything specific. That really opens it up. ;) Simh emulates several platforms for which there are DECnet implementations: PDP-8: there's a DECnet implementation for OS/8. PDP-10: TOPS-10, TOPS-20 PDP-11: RSTS/E, RSX-11/M/M+ VAX: VMS, Ultrix The PDP-8 DECnet is actually for RTS-8, and not OS/8. However, it's also only PHASE II, so I think we could rule that one out. For PDP-11, I think that there was also some kind of DECnet for RT-11. And you have IAS, as well as (probably) RSX-11D. Also, I wonder if VAXELN also had DECnet? And isn't there some sort of Alpha in simh as well nowadays?
