and the US don't lose or destroy it). So I definitely want to make a
backup copy.
Is this possible to do with only one drive? Apparently you can't swap
disks back and forth like the old DOS or CP/M systems. Henk thinks
creating a RAM disk would work, and copy files but I don't know
anything about RT-11.
The alternative is to take the RL02 from my PDP-8/A and connect it,
but then I don't have a "1" key, they are both unit "0".
You could dump it over vtserver (very slow) and copy to the new pack.
That's how I got XXDP onto a scratch pack.
