RT-11

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/

INITIALIZE (format floppy)

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.

.RUN DUNGEO

front door.

@ command

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

.@STARTS.COM

.D 56=5015

.TYPE V4USER.TXT
Welcome to RT-11 Version 4. RT-11 V04 provides new hardware support
and some major enhancements over Version 3B.

Please use the HELP command;  it describes the new options in many
of the utilities.

If you are using a terminal that requires fill characters,
modify location 56 with a Deposit command before proceeding with
system installation. LA36 DECwriter II and VT52 DECscope terminals
do NOT require such modification.

Squish command

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

.SQU

RK0:/Squeeze; Are you sure? Y
