In the spring of 2004, I received a call from a couple whose old Mac SE had just packed it in. They wanted to know if I could repair it, as they still used it for playing solitaire and doing their book-keeping. I agreed to pick it up and see what I could do. When I arrived at their residence, I found that the machine was completely non-functional. I also found that they were pack-a-day smokers, who used the top of their SE as a convenient ash-tray stand. I told them I would see what I could do, but it was getting harder and harder to find parts for the older machines, and I had gotten rid of my stock of Mac SE parts.
Two days later, I was contacted by someone who wanted to dispose of their old Mac SE. I went to see this machine, and found that it was in perfect running order, and pristinely kept. And exactly the same model for which I was needing parts.
Rather than try to figure out which part of the non-functional machine had failed, I decided I would simply remove the hard drive from the failed machine and "transplant" it into the working one. I took the following pictures after I cracked open both cases. These pictures provide a graphic example of why NOT to smoke around your computer.
