Thanks Dave. Another listmember has given me the required incantations. Excellent. It was looking good for the IGS for a while. To my surprise, it turned out to have DECnet capable software. Unfortunately, it was too good to last. This machine is now looking a bit sick. It keeps rebooting and not getting past the first two lines of the startup banner. Hmm, that's not good. If memory serves, in an IGS, IOS resides in a bank of EPROMs and the memory is in the form of 30-pin SIMMs. I'd try re-seating those and see how far you get. The 1600 does not have DECnet capable software. Perhaps Brian can help out here. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
