When I started my first full time job at City Hall in 1990:
-Everyone was allowed to smoke at their desk.
-Amonia blueprint machines were the norm.
-AutoCAD 9 was the platform
-Windows 3.1 was uncommon on most PC machines. Few people ran DOS based WordPerfect, everyone else worked on green CRT IBM AS/400 workstations.
-The one "official zoning map" was updated on mylar with zip-tone adhesive patterns.
-Some Department Heads were known to keep a bottle of brandy in their desk drawer.
