I'm not sure where I got this one from, but this, along with the Lisa, is one of my favorite computers in my collection. It was quite advanced at time time with a powerful - but poorly named - OS, (Sophisticated Operating System, or SOS), but it wasn't horribly successful in the marketplace - although I gather that "failure" is too strong a word. It seems to have been somewhat forgotten, but I like the case design and, as mentioned, the operating system.
