The MIT AI lab got their PDP-6 first.  1964ish?  Then they added a
KA10 in 1967.  The DM group got their PDP-6 in 1969 and added a KA10
the year after.  The Mathlab people wanted their own machine, so MIT
got a third KA10 in the early 70s.  AI and ML got pagers and used the
same ITS version.  The DM straggled behind without paging for a while.
In 1975 the Macsyma people wanted a faster machine, so MIT got a KL10:
MC.  The DM PDP-6 were never used that much.  I don't know when it
went away.  The AI PDP-6 was disconnected from the PDP-10 in 1978.
Around 1983 all three KA10s were struggling and where shut down.  Only
MC remained for a while.  Then the AI lab got a KS10 in 1984.  ITS up
and running early 85.  Three more KS10 appeared: new ML, MX, and MD
(the DM was taken by a VAX).  MX was pressed into service as the new
mail server, and traded name with MC.  MX, now the KL10, went to
Sweden in 1988.  I don't know about DM and ML, but ML and AI kept
running until 1990.
