[HECnet] KLH-10 TOPS-10 DECnet Executor Configuration Persistence

I don't think it would be a terrible idea to understand just a little bit more to know what start up files to edit, but I certainly do understand not wanting to be bothered with something.? If I remember any more, I'll let you know.

The new SIMH port appears to allow for a slaved PDP-6, which I remember seeing on the 9th floor (It was connected to the MIT AI KA-10).? I think they only shared one moby.? The last I heard was that the KL sources to ITS (MC) were lost.? Anyway, if the SIMH KL simulator allows multiple CPU's, then you could run Tops-10 SMP, which really was a tour de force.? Extremely cool.
