In the first set of two photos, the tall cabinet  with the Teletype
to its left is an Alphanumeric Corp. "Alphanumeric  Photocomposition System"
("APS") - possibly an APS-2, probably not an  APS-3.  It look as if it
might be built out of DEC equipment, but I  don't know my DEC equipment
very  well.
________________________________________

The DEC equipment in  the photo from Ebay item 380804797518
is a PDP-8 computer (rackmount  configuration) with a TC01
DECtape controller and dual TU55 DECtape  drives.  Compare
this with this photo of the system I'm working to  restore:

The  first rack is identical.  The second rack is different -- I have  an
analog-to-digital converter, where that rack has the  DECtape
equipment.  The rack itself, however, is the same -- and since  DEC
didn't offer other colors, the color of the rack is the same.

My  rack is missing the table.  the DEC catalog has the dimensions
of the  table, as seen from the top, but no construction details.
The man who was  hired in 1966 to program the machine remembers
that there was an attached  table, I'd love to get an underside view of
that table to see how it's  built in the hopes of replicating it.
