An ex-DEC engineer offloaded some strange stuff that

I just thought I could have a look. But what is it?
There is two backplanes marked KA14 and BE14. I thought it was the PDP-14,
but I am not sure really.
Bitsavers Options_and_Modules_List_197406.pdf contains
the BE14 and KA14
as PDP 14, I'd guess that too.? Just looked up the M743 module, and it
is reference to the same.
They match blocks I have from PDP 11 though, not sure of the history of
the PDP 14 at this point, maybe shared the hardware.

I came together with a similar sized PSU.
Then there was a strange DEC workshop built paper tape reader. The reader
mechanics looks similar to PC04 and PC05 but is smaller. The wheel is
smaller and the stepper motor is smaller as well. Are these parts from some
other DEC reader they cobbled together at DEC for inhouse duty.

Someone saved the bits and pieces of a reader from
the looks of it w/o
the front mounting plate.
Any clues?
