What is the media that you're trying to install from? TK50? Actually right now I'm doing it on simh - it's faster for "trial and error" experiments than the real hardware. But I do have a 11/53+ w/ 3.5MB, 2xRA73s and a TK70 that I plan to eventually install it all on. Are you going to get a RSTS/E 10.1 system up on HECnet? Eventually, yes, although it probably won't run 24x7. I don't have the necessary cooling to run mine. :^( In the Pacific Northwest electricity is cheap - here in CA I can't afford the power to feed all these machines! Bob
