Source Code

These source-code files were derived originally from the scan from MIT's Dibner Institute's now-discontinued website titled "History of Recent Science and Technology". It is believed that the original listing was preserved by AGC developer Don Eyles, copied/reduced by AGC developer Hugh Blair-Smith, passed by AGC developer James Kernan to collector David Craig, scanned by Gary Neff, and then passed to the Dibner Institute where unfortunately the high-quality scans were reduced in legibility as part of the online-presentation process, and the original scans discarded. The source code was transcribed from those images by Ron Burkey. The images from the Dibner Institute website, and unfortunately not the discarded original high-quality scans, though with a few high-quality replacement scans provided directly by Gary Neff, are now available at the Virtual AGC project website.
