A comment from the blog item caught my eye:
In several cases, the listings represent point‑in‑time working states and hand-written notes, preserved by Tim Paterson himself. Think of them as a printed commit history of a Git repository. They create a timeline of changes ....
In 2026 the blogger felt that a 1980 stack of paper source listings with hand notations, needed an explanation as a kind of non-digital archive. Part of the backstory is about OCRing those listings for an accessible digital archive & distribution. Relative to the recent VCF-East, very few printers were in exhibits, a handful offered in consignment (a DEC LA36 was for sale, fate unknown). These remind me how dead paper and paper printing are today for most computerists (that is, everyone not an adult in 1980). In the era, the automation of text-on-paper and desktop (paper) publishing were a revolution; today they are marginal history, a recovery challenge, an explanatory footnote. Regards Herb Johnson
