Build procedure

  1. First, magnetic tape images are created from files in src and bin. There are two bootable tapes, and two tapes with files in DUMP backup format.

  2. Then the tapes are used to create a file system on an RP06 disk and populate it with a minimal system.

  3. Next, the system is booted from the disk. Source code is loaded from tape, and the following programs are rebuilt:

    • MIDAS, the assembler.
    • DDT, debugger and HACTRN user login shell.
    • The ITS monitor (kernel).
    • Exec DDT, standalone debugger.
    • NSALV, standalone file system tool.
    • DSKDMP, disk bootstrap and file access.
    • KSFEDR, manipulate front-end file system.

  4. The new DSKDMP is installed, and the rebuilt monitor and salvager are combined into a new ITS binary, which is then started.

  5. Remaining programs are rebuilt.

  6. A brand new host table is built from the host table source and installed into SYSBIN; HOSTS3 > using H3MAKE.

  7. Finally, the whole file system is dumped to tape.
