How can I efficiently copy files from my host system to unix version 6
running in the pdp11 emulator and from unix 6 to my host system?
You have gotten a number of answers, but none of them strikes me as the
best method for what you want to do.
There is a raw 8-bit device (well, pair of devices) on the PDP-11 which
will do the trick: The paper tape reader/punch. Simply cat the file onto
a paper tape image, or cat it from a paper tape image into a file. Won't
care whether it's text or binary. Won't revise the content to match a
display (\t will stay \t).
I've used this in the past. It works.

Rich,
This looks like the easiest method for text so far. However, I am
getting interesting results that I hope ring a bell for you or someone
else listening in...
I edit a text file on the host
vi ptr.txt
Hello World
fire up the simulator and:
simh> attach ptr ptr.txt
simh> attach ptp ptp.txt
co
# cat > hello < /dev/ppt
# cat hello
Hello World
Yee ha, I can read from paper tape.
cat hello > /dev/ppt
Bummer, nothing is written to ptp.txt. Well, as it turns out, the data
is sent to the tape, but it doesn't appear in the file until I suspend
the simulation with CTRL-E.
I tried sync's and waiting and no go. CTRL-E, immediately writes the
file. Does this sound like expected behavior or perhaps a bug?
It still works, mind you. I don't really mind suspending the instance
after a sync or two, but it isn't ideal.
Thanks,
Will
