 This is a picture from the late 1960s of the LDX:

The CMU one was first online (shortly) followed by MIT and then Stanford
about 6 mons later.
Here are two of my favorite pics: loading TP into the XGP:

and the output =- small diplomas:

Fun story about the PARC/Adobe's late Charles Geschke.  His Ph.D. thesis
was the first to be printed on it.  CMU's Library initially rejected it and
would not grant him his diploma, because they wanted the hand-typed masters
for their archives.    It took many months and lots of pleas from folks in
the CS Department to get him an exception - trying to explain they the
library had the master already.
