      Hi Herb,
      Sorry for not getting the Dr Dobb's reference sooner... I couldn't figure out which issue it was in until I happened to be
      looking at some corrections to the PATB code in the June/July 1976 issue, page 34.  After looking at the short
      article again, there really isn't any computer focus at all, just "if you have any suggestions, send them to...".
      Not much of interest after all.

      I'm still documenting the system, first of all. Second, my initial
      understanding is that this system was used by the DEVELOPERS at NBS
      who developed some of those scanning systems used by the Census
      Bureau. Many computers were used of course by the Census Bureau, at
      many locations - I've read as much. As for the Dr. Dobb's article, I'd
      appreciate a specific reference so I could look it up.
