Nice piece of vintage computing! That's one of the more interesting models, with its collection of unique internal parts.
To those who wonder "what good is it?"
This is the "Apple Collectors" sub-forum. This is specifically for people who collect Apple gear. That includes older gear.
Nothing says it has to be "useful" as an everyday machine. There are people who collect many different types of items, vintage computers are just one kind.
It could be for nostalgia (I have an old Apple IIc that I use to play old games like Oregon Trail and Where In The World Is Carmen Sandiego,) it could be because you want to learn more about what came before, it could be just because you like how they look.
