README.md

Tools for analysing PDP-10 ITS files.

  • Disassembler for ITS executables.
  • Extract files from an ITS archive file.
  • Extract files from Alan Snyder's IPAK archives.
  • View contents, and make MAGDMP tape images.
  • View disk image contents.
  • Extract files from a DECtape image in MACDMP format.
  • Create a MACDMP image.
  • Print the contents of SYSENG; MACRO TAPES and .TAPEn; TAPE nnn files.
  • Convert PALX binary to PDP-11 paper tape image.
  • Convert CROSS binary to Atari DOS binary.
  • Convert files to a RP04 bootable KLDCP disk image.
  • Scramble or unscramble an encrypted file.
  • Make a picture file suitable for displaying on a Knight TV.
  • Write out a core image in some of the supported executable formats.
  • Analyze a CONSTANTS area.

A Linux FUSE implementation of the networking filesystem protocol MLDEV is elsewhere: http://github.com/larsbrinkhoff/mldev

Tools for other PDP-10 systems.

  • List or extract files from a TITO tape (Tymshare TYMCOM-X).
  • List, extract, or write files on a DART tape (SAIL WAITS).
  • Write files on a DUMPER tape (BBN TENEX, DEC TOPS-20).
  • Add or delete DEC-style text file line numbers.
  • Extract files from a DECtape image in TENDMP/DTBOOT format.
  • Create a TENDMP/DTBOOT image.
  • Print entried in a WAITS accounting file.

File formats supported.

Most tools support these PDP-10 36-bit word encodings:

  • ASCII text, with an additional bit stored in every fifth character.
  • Binary image.
  • Core dump 9-track tape format.
  • DATA8, one 36-bit word stored right aligned per little endian 64-bit word.
  • DTA, DECtape image.
  • FASL, Maclisp compiled fast load files.
  • ITS evacuate format.
  • Octal digits.
  • Paper tape image.
  • Saildart.org UTF-8.
  • Tape images, 7 or 9 track.
  • Files stored in an Alto file system.

Most tools that work with executable programs support these formats:

  • ITS PDUMP and SBLK.
  • Muddle/MDL save files.
  • Raw files.
  • Read-in mode.
  • Stanford WAITS .DMP files.
  • TOPS-10 and TOPS-20 nonsharable/compressed save .SAV files.
  • TOPS-10 highseg sharable .SHR and nonsharable .HGH format.
  • TOPS-20 and TOPS-10 sharable save .EXE files.
  • TENEX sharable save .SAV files.

In addition, some mini and micro computer program formats are supported:

  • PDP-11 PALX binaries.
  • PDP-11 absolute loader tapes.
  • CROSS binaries.
  • CROSS "ASCII HEX" files.
  • Atari DOS executables.
  • Imlac "speciall TTY" files.
  • Harris HCX/UX cpio.
