From an anonymous source close to the company, I've found myself in
possession of the "Infocom Drive" ? 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.
For obvious reasons, I can't share the whole Infocom Drive. But I /have
to/ share some of the best parts. It's just /too good/.

There are downloads of the Milliways game at the bottom of the web page,
right before the comments. You'll need a Z-Machine interpreter to play
them, as usual.
