I recently recovered code that I wrote 23 years ago in middle school. It was for an Apple II BBS we ran for a little while.

To read source code (and BBS messages) that you wrote in 1989 as a kid is quite a surreal experience, to say the least.

I got the code running, too, thanks to an email I wrote to a friend on said BBS describing in detail how to edit the code (using the AppleWorks word processor), recompile the code, and operate the BBS from the console. Without that 23-year-old email there's no way I would have ever figured it out.
