From an anonymous source close to the company, I've found myself in possession of the "Infocom Drive" â€” a complete backup of Infocom's shared network drive from 1989. This is one of the most amazing archives I've ever seen, a treasure chest documenting the rise and fall of the legendary interactive fiction game company. Among the assets included: design documents, email archives, employee phone numbers, sales figures, internal meeting notes, corporate newsletters, and the source code and game files for every released and unreleased game Infocom made.
It's a VERY long read, but has tons of interesting stuff from way back when.
