This document says MIT's Lab for Nuclear Sience was busy working with
their PDP-6 in early 1970. So that could not be the used machine the
DynaMod group got in late 1969. That is, if those dates are accurate.

By the way, the Australian ITS called FU is a great mystery. I only

XCT is present in all PDP-10 processors. From the KI10 and onwards it
includes PXCT, since these have the concept of a previous context...
