Welcome

You are being served by an HTTP server hosted by the NOS 2.8.7 Operating System running on an (emulated) Control Data CYBER 180/870 The CYBER 870 is a large dual CPU Cyber 180 mainframe with 128MB of central memory. 16MB of that is dedicated to NOS with another 8MB dedicated to UEM for CYBIS. the rest of the memory is used by NOS/VE when it is running.

The 180 CPU runs both the CYBER 170 mode instructions and 180 mode native 64 bit virtual memory instructions sharing two operating systems on the same processor in a mode known as dual-state. You can read up on the 180 here and also on bitsavers.

This system is being run under emulation by DtCyber

Getting started with NOS

I recommend reading NOS Reference set Volume 2 first and then NOS Reference set Volume 1 for interactive usage.

Volume 4 is for programmers and Volume 3 is a comprehensive reference for all the commands including a lot of information that is in volume 2.

Online Manuals

There's also a collection of online manuals that you can read by using the
EXPLAIN. command when logged into an interactive session. EXPLAIN is a lot like
GNU Info.

For the SES tools and CYBIL online manuals use the SES.EXPLAIN command and folow the menu.

Using the full screen editor (interactive mode only)

first type screen,webtrm. then follow the FSE user's guide.

Useful FSE commands

commands are typed into the upper lefthand corner of the FSE display.

st 2 11 18 30 72 - set up tabs for COMPASS
st 6 7 73 - set up tabs for fortran
set view col 80 - switch to 80 column mode
set view col 132 - switch to 132 column mode

PLATO interactive lessons

There are interactive PLATO lessons on how to use NOS and program in COMPASS and FORTRAN, etc.

To take these lessons go to the NCC CYBIS Login and login with the following user/group combinations:

nosguide/cnos - lessons on the NOS operating system
nosts/cnosts - lessons on how to use the NOS interactive facility
fortran/cfortran - lessons on how to use fortran on the cyber
fortran/ccrm - lessons on how to use the cyber record manager for fortran users
compass/compass - lessons on how to program in the COMPASS assembler.

FORTRAN test mode compiler

This system exposes a special test mode build of the FTN4 and FTN5 compilers. Example jobs are provided under the Remote job entry station interface if you click on the compose job button.

The source code to the compilers is provided as zip files for study under the manuals link inside the FTN5 and FTN4 directories. Internals documentation is also provided along with user documentation.

Getting Started with NOS/VE

To login to NOS/VE log into the guest account under NOS IAF and then type HELLO,VEIAF and press return you will be logged into NOS/VE you can use the explain command just like in NOS to read online manuals. you can also read some NOS/VE manuals here

I recommend reading

Migration from NOS to NOS/VE
NOS/VE System Usage
NOS/VE Commands and functions Quick Reference (also availble through the explain command)

Run your own cyber

The emulator that this site runs on is Open Source and includes ready to run operating system kits and software.
