Indeed they must be. I've been looking for /40 ALDs for some time but haven't struck any. I wonder if they're
scarce becase the 40 was a AFAIK a british-developed 360. My dad was posted to Hursley to learn the /40 in 64-65.

The only Model 40 docs I have left are less than a dozen pages of 'IBM SYSTEM/360 MODEL 40 DEVELOPMENT MANUAL'
from March 1965 from 'IBM BRITISH LABORATORIES'.
Why do I have these? Dad used to bring home Model 40 binders in the late 60s so my brother and I had a good
supply of paper to scribble and paint on as kids. All the pages I have left have drawings on the blank side
and that was why my parents kept them :)
