I don't have nearly enough time to look at all of these *really* old tech reports, but just scanning the author names reveals once again Xerox PARC's amazing impact on computing. Gifford, Guttag, Zellweger, Geschke, Card, Norman, Boyer & Moore's string matching paper, Bobrow, Warnock, Kay, Demers, etc. etc.
Need I say more.
Memo to self: don't know how long this archive will stick around, but it might be worth a crawl
