The best information I can find is that PDP-6 ITS was first operational in July 1967. See AIM-138 (mentions TS and non-TS LISP), and Project MAC Progress Report IV.

ITS version 350 was clearly running on the PDP-6. See AIM-161 from June 1968.

AIM-161A dated July 1969 mentions PDP-10, though it seems the PDP-6 was the primary timesharing host. This could be the first AI memo to mention the PDP-10. The ITS version at this time was 530.

Open questions:

  • When did ITS switch over to the PDP-10 as the primary host?
  • When was virtual memory in operation?

http://bitsavers.org/pdf/mit/ai/aim/AIM-200.pdf mentions the 6 and 10 on equal terms. Says pager to be completed early 1970, which is consistent with HW memo 2.

I'm hoping to get the ML tape 1054 file SYSBIN; ITS CPY dated 1974-05-01. It may be the only preserved 1974 version of ITS.

ITS has a symbol called ASMDAT with this definition: ASMDAT==.OP <.OPER@> 0,.RDATE

TODO: Check all old binaries to see when they were assembled.

There are also ITSVRS, MAGVRS, and IMPVRS which have the file versions for ITS, MTAPE, and IMP.

Where do you see this symbol, ASMDAT? I don't see it in the current ITS sources, nor as a symbol in the ITS symbol table.

I see it in ITS versions 724-864. But not in 1041, so apparently it was removed.

I'm working my way backwards from 785 sources. I have edited them to get exactly matching binaries for 781, 776, 776, and 771 so far. I'll do 768 and ultimately 724 too. At some point I'll go the other direction and make sources for 848 and 864, but I'll wait until I have more files from SYSTEM.

There is one problem: CONSTANTS leave one extra zero at the end. I don't know why. I have hacked around it by inserting essentially LOC .-1 after. This happens with all MIDAS versions 135, 324, and 458 so it's consistent.

I don't think it's appropriate to store the files in this repository, so I created this which also makes a chronological git history: https://github.com/larsbrinkhoff/its-history

@gjs found his hardcopy listings for ITS 138, Maclisp 97, and a Maclisp compiler. According to the book The Tomorrow Makers, the ITS listing is from 1967 which seems consistent with other information. AI memo 161 from June 1968 has the next earliest recorded version: 350.

There was a Maclisp 107B in December 1969, so maybe 97 could be from 1968-69?
