Finally I removed the Foxboro paper tape reader. The tape holders each
side slide up to reveal the rack mounting
screws. Onto the ute it went.
There were some other racks of gear, but all custom idustrial control
equipment. One rack had a DEC A-D Converter
in it with some serious cables connected to some backplanes of the smaller
Flip Chip modules. I grabbed the A-D
and Flip Chips.

What is in picture 18? There is something very familiar with it. To me it
looks like the backplane of a PDP-9. The core memory stack in the top.
Compare with the RICM PDP-9:

I would be very interesting to see more pictures of the cabinet in picture
18.
I also would guess that the the cabinet with the A/D converter (AF01A) in
the top also hold a D/A converter (AA01A). It looks very much similar to
the one we have with our PDP-9.
