I found this text:

    Full ITS first ran on the AI PDP6, and was ported to the DM PDP6.
    Later, PDP10s became available, and the labs acquired some of the
    earliest ones -- the AI-KA10 (AI Lab's machine), the ML KA-10 (used
    by the MathLab, Theory of Computation, Automatic Programming, and
    certain other LCS gruops), and the DMS KA-10 (Dynamic Modeling
    systems, also used by certain other LCS groups); these replaced the
    PDP-6s, which were slowly phased out.

So it seems the DM PDP-6 indeed ran ITS, at least for a while.
