What is a PDT-11? I just got one new in the box with 7,000+ pounds of other
brand new (1965-1978) dec stuff.

It has two TU-60s and looks like a VT100.

As I am damn near dead and *very* sick... and my family and I had to load
the stuff ourselves(last 2 days)... I am not able to list contents yet but
.. "TU-56 units a-plenty". I will post pictures soon. I guess I don't have
to say a Christmas tree this year is simply out of the question now.....

[will be back online in a day or so when we get the trucks unloaded]
