RT-11 installation

Oops. I made a mistake in my original post. The command I typed to copy
the distribution disk was:


That's what the installation instructions say to do anyway.

I've actually gotten a boot disk created now. It seems that the V4
version of RT-11 I was originally using didn't really do the COPY/BOOT
command correctly. I found another V4 boot disk and was able to use it
to create a bootable V5 disk. I now have RT-11 V5 and the DECUS C
compiler and linker all on one disk. This is something I could never do
with my old PDT-11/150. It only had RX01 floppies and all that won't
fit on a single density floppy. It's nice to have a bit more space with
RX02 drives!

Thanks for your help!
