Ken,
Thanks for this Herculean/Googlesque feat of scanning!
It looks like we now have all our ALDs scanned for both 1401 systems!(?)
Plus most/all(?) of the potpourri of other hardware docs that we have in the racks.

Robert, I've scanned all the ALDs and most of the docs in the back room. I skipped some of documents
that already had versions online. I only scanned a couple of the 729 manuals since they are all
fairly similar, and the paper doesn't work well with the scanner's auto-feeder. If there's anything missing that you want scanned, just let me know.
The most interesting document I came across was the Machine Record Card for the CT 1401, which
lists the service visits and when all the different features were added. For instance,
in February 1963, the 1406 storage and the multiplication/division feature were added.

I’m not sure how I can adequately thank you via email, but THANK YOU !!!
(How many hours of scanning did this take? Whose scanner did you use?
Did you scan the original ALDs from storage or the copies in our lab?)

Scanning took a lot more time than I expected. I used a Ricoh scanner at Google that feeds pages
and scans pretty fast. One problem is the ALDs are full of post-it notes, punch cards used as
bookmarks, and relay contacts taped to a page (seriously), so I had to do a fair amount of removing stuff and putting it back (in case it was important). Assembling the scanned pages back
into PDFs was also a lot harder than I expected. Part of the problem was the scanner breaks the
scans into chunks of about 15 pages.
I didn't take good notes as I was scanning, so I had to keep going back to the lab to figure
out which scans were part of which documents. I wanted to include OCR so I used Omnipage, but it is a difficult piece of software. I ended up writing some C# programs to manipulate the PDFs
the way I wanted. Now that I have everything mostly figured out, I can scan things pretty fast.
The take-away message from this to anyone else doing scans is setting up the process/workflow was the hard part.
I used the ALD copies from the lab, so the quality is not the best. The scans do a pretty
good job of replicating the bad quality of the ALDs in the lab :-)
