Here’s a 25 35 year old puzzle (it’s not mine). I’m curious if you’ll find the solution without using Google.
First one to post a comment with the solution gets a sticker (and I’ll have “PDF – Penetration Document Format” stickers soon). But play fair and don’t post your solution if you just Googled the bit sequence.
