RT-11 was an OS for the PDP-11. Overall it has a very OS/8 feel to it.

notes

The filesystem was like that of OS/8 in that files are stored complete on the disk, so that if you delete them the disk will need to be 'squished' back down. http://www.vaxdungeon.com/

Commands

These are a few commands that I've managed to work out, in no particular order.

DIR command

Just like MS-DOS

RUN command

Dungeon for example is executed with RUN. I think you have to run .sav files.

@ command

COM files are like batch scripts, and are executed with the @ infront of them.

Squish command

Disks will need to be 'defraged' or compacted with this command. In some version it'll just be SQU.

.SQU
Device? DK0:
RK0:/Squeeze; Are you sure? Y

SHOW command

This is a very usefull command to show some info about the OS.

.SHOW
TT
RK  (Resident)
    RK0 = SY , DK
