I always thought there was one and only one PDP-6 at MIT.  The one
running ITS at the AI Lab.  But then I found a post to alt.sys.pdp10 by
Marc Crispin:

Digging further, I found Project MAC progress reports mentioning this
Dynamic Modeling PDP-6.

Does anyone know more about this PDP-6?  Did it ever run ITS, like its
PDP-10 successor?
