Okay, you degenerates! Let’s see how much you really know about the history of Unix.

— try to do the quiz yourself first, spoilers follow —

I’m doing the quiz for 2 days now, and a few hundred Google queries and digging in old archives and tapes later, I found out about 66% (I already knew 15%). It is tough. Here are my answers. Questions marked with “?” are not yet answered, questions marked with ”*” I knew without looking.

Thanks to Lincoln Quirk, questions 4, 8, 9 and 10 could be answered.

Thanks to Eric Cooper, question 37 could be answered.

Huge thanks to George Rosamond, who sent in the official solution from ;login: Volume 9, Number 4 (September 1984), which was provided to him by Brian Redman!
