Can you tell me a bit more about this virtual tape creation? I have a few PDP11's working but they all run DSM It's the only Digital operating system I know - I never used RSX RT11 and so... I also have a 9track tapecontroller for pc and a Kennedy 9600 drive on it but this was used on MSM (the pc version of DSM made by Micronetics)and they controlled the drive direct without os intervention.

I use SIMH and I should like to manage DSM some time :-) Cheers Sergio
