Re: [Simh] PDP11 on Simh for public access

SAV files would be binaries (RT11 format). BAS are source files. There are a number of solutions. Text files you could load via paper tape, with the text file attached to the SIMH tape reader. That's not as good an answer for binaries though it could be made to work. Magtape or disk are

Too bad, I thought at least presetting date/time would work that far back. How about using a Telnet connection for the console, that's a SIMH feature. Then you can connect to it with a tool to drive the data to the console for startup, then once that's done disconnect and reconnect with a
