|That's a very large topic. When I send out login information for new accounts on our systems, I include references to "Getting Started with DECsystem-10" and the Tops-20 User's Guide at bitsavers.org. These provide basic user-level information on the DEC-supplied operating systems which we run on our two systems. Other manuals at the same location can provide more in-depth information on various topics. |
If you are interested in programming on these systems, you have a fairly wide range of choices: FORTRAN, COBOL, BASIC, LISP, Algol, BLISS, C, SAIL, or if you prefer assembler Macro (DEC), FAIL (Stanford AI Lab), or MIDAS (MIT AI Lab). For the really hardcore, you can learn to program in TECO, either the DEC version on Tops-10 or the even more powerful MIT version on Tops-20. (The latter is the implementation and augmentation language for the original EMACS editor.)
If you want to learn how to run a PDP-10 system, whether under a DEC-supplied operating system or under the Incompatible Timesharing System (ITS) from MIT, you need to familiarize yourself with the installation and operations documentation for the OS you choose. These can be found at the bitsavers.org website.
