This is the Macintosh SE that we had as a family computer since it was new in 1987. As a youth, I absolutely loved this machine but I always was bothered by how slow it was, especially after upgrading it to System 7. Today, I'm going to fix that be trying to install a mysterious vintage accelerator into it to see how much of a boost it can really get.
