As Paul said. ALDs are schematics down to the gate level basically. Necessary to make a
gate exact emulation, or debug and maintain a real machine. Used to be sent with each and
every machine, but sadly not often preserved apparently. Fortunately our IBM 1401?s came
with their ALDs. We refer to them every time so something goes wrong.

What does ALD stand for?
Bill Which brings us to the real problem: we don?t
have 360 Model 50 ALDs.
Anyone has them?
Marc
And same for the Model 40 ALDs. All I
have is one or two pages of the 2040
ALD's and some peripheral ALD's only
saved because I'd drawn artwork on the back, or they got used for book
covering.
I've not scanned them yet but should get to that sometime. Sadly there's
not much there. A while ago I did scan a
tiny fragment of the Model 40 development doc from Hursley
