I looked in a drawer just now, looking for them, and found the certification report for my first computer. A 486 with a whopping 16 megabytes of RAM. I got down about as far as 1994 (I knew because I found 21st birthday cards), at which point I realised it was a fruitless search and turned back. There weren't just dust bunnies in there, there were dust elephants.
I am gradually tidying, honest.
