RT-11 with Basic-11

I have now managed to get a boot disk with RT-11 and BASIC-11 on it (thanks Mark for making *another* boot disk on your PC).  So now I can boot my PDP and write programs on it.  Progress indeed.  Here is something I captured running on my actual PDP-11/53:

...as you can also see, I have also been busy experimenting with the best colours for my terminal emulator.  Today I am mostly programming with grey text on a blue background.  Getting this to work involved taking two 400k RX50 disk images and creating a single 1.2Mb RX33 image.  So I effectively merged the contents of the RT-11XM boot disk and the "Languages Master" disk into a single boot disk.  Works a treat.  This seems to boot much faster now, so I suppose the RX33 drive is much faster at reading 1.2Mb 5.25" floppy disks.
