[Simh] Dec-10 Day announcement from Living Computers: Museum + Labs

[Johnny Billquist]

Rich. This is a nice thing. Thanks.

I have one question/wish, though.
I don't know if you were aware of a device called the RM06. This was a 
Massbus disk created by Shelby, which was varible size.
It would be a really nice thing to emulate. I can probably reverse 
engineer it from the RSX driver, and I don't know which systems ever 
supported it. RSX for sure. Possibly also RSTS/E, but beyond that is 
more uncertain. Most people and systems had moved on from Massbus before 
this drive came out.
But it is a much nicer solution than emulating eight RP06 drives, when 
you have some big disk in the backend.

Do you know what speeds this emulated massbus disk can achieve, by the way?
