RT-11 installation

[David Betz]

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

SQUEEZE/WAIT/OUTPUT:DY1: DY0:

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!
