I also took some time to observe Richard’s picture of the original DND1, which includes three paper tape rolls with the program (probably different versions?) as well as a beautiful, ages old sheet of paper containing original input from the program.
In making the transcription, I *think* I have discovered something useful; there seems to have been more than one version of DND1! the version whose output is printed on that page is definitively an enhanced version over the one whose source code we finally got, it’s possible that the final DND1 had indeed character based maps, similar to the sample on the contest entry!
But there are just fun conjectures, who knows?
