No, but I did find myself in the mid 90s as an intern trying to figure out code from the early 80s. It was really tricky code to get ECG processing working on some very small memory footprint or something. The name of the woman that wrote it was at the top of the file, and I looked her up in the HP company directory and she still worked there. As a hail-mary, I emailed her and asked a question about it. And she immediately got back to me with the answer. So, there are some engineers out there that do remember this sort of thing.
