A shorter title would be appreciated.

An attempt to bring together information from various sources, about version numbers for prominent ITS and pre-ITS software. This includes references to version number and/or dating information, even though the code itself is no longer available. Such data items are marked "version", whereas preserved files are marked "source" or "binary" (as applicable).

Many programs were created on the PDP-6 (or PDP-1, or TX-0) before ITS, and were gradually or abruptly migrated to run under time-sharing. The non-timesharing versions are marked with "NTS".

A note about ITS program versions

Version numbers for ITS and related software do not work exactly like we are used to today, where a version number is associated with a release of a program whose code is fixed. The ITS version numbers are more like file edit versions, or build numbers. A program takes its version from the source file version. When in use, the binary is updated with binary patches, and those updates are also noted on the paper listing, and/or in the source file. At some point, a fresh new binary is built from the source file, which may at that point have added one to the version, or sometimes more if intermediate edits were made.

ITS

Since there are hundreds of versions of ITS, this table focuses on preserved files and version information below version 688. From then on, comprehensive ITS version history has been recorded in the backup database. See ITS versions

DDT

DDT by that name was first created on the RLE PDP-1, but even before that the UT3 program on the TX-0 was a similar type of program.

The history of DDT on the AI lab PDP-6 is somewhat muddled. There first was a non-timesharing DDT; it was still in use later, mostly for booting and debugging ITS. The timesharing DDT evolved from NTS DDT, but the latter received some updates over the years. The most obvious link is the DECtape "@ HACTRN" file which is clearly NTS DDT ported over to make timesharing system calls rather than direct IOT instructions. There is also the matter that HACTRN was initially envisioned by Greenblatt to be an entirely unrelated program with an interface more similar to TECO. However, Knight's "multi procedure DDT" won out. Most files called HACTRN are DDT, but some might be code from the other.

This table lists versions up to 285, after which there are plenty of files preserved in the ToTS archive.
