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
