As others have mentioned, the Panda distribution uses KLH10 not simh. It's supposed to come with a precompiled klh10 executable for Linux and Intel. It also comes with a pre-installed, ready to boot, system image that you can use after some minimal configuration, and there's README file that describes how to boot and configure it. I've got to admit that it's been a while since I tried it, but I don't remember any problems. What's the issue you're having? As for Linux DECnet, I'm afraid this has absolutely no connection. The Linux DECnet package allows a Linux machine to speak DECnet natively (well, more or less) so a Linux machine can participate as a node in a DECnet network. This is independent of any simulations or simulated operating systems. If you have a lot of DEC machines, it's very handy to be able access your Linux machines with FAL/NFT, SET HOST, NCP/NML, etc. Bob
