Just checked the list of 18 bits installations that Bob Supnik made
There is a PDP-9, s/n 209 delivered to Australia Iron & Steel.
It had a AF01B (A/D converter) s/n 195 and a AA05B (I am not sure how it
differs from AA01) s/n 101. It is also supposed have an extra memory
cabinet since it had two memory stacks.
There are also two items which I would guess is non standard options: "76
05404" and "76 05426".
Check the AF01 you got is matching the serial number.
It was delivered in 1969.
There are a few flexiprint cables dangling in the foreground. I think those
are the ones that are supposed to connect with the front panel. So someone
has probably taken the frontpanel. Maybe that is way it is not recognised
as a PDP-9.
