LOTS of model /40s were sold in the US. EVERY one had
its
own set of ALDs, with the serial number of the CPU on them.
They not only recorded the general info for the model, but
they had specific changes to reflect the exact configuration
of THAT machine.
I didn't know that every machine came with a set of ALDs but you are
right that a lot of /40's were sold stateside. My dad was re-posted
directly from Hursley to Poughkeepsie in '65 which I was where some (or
all?) the /40s were assembled.
One of the IBM Journals (75 years?) has a large colour photo of a row
of 40s on the final assembly floor at Poughkeepsie, everyone in it
striking that characteristic 60s/70s IBM-photo-pose, eg. someone leaning
over a table, another reaching for a console knob, one changing a tape and
at least two people earnestly discussing a printout.
