Apple //GS just boops
I found a //GS that someone was discarding. I plug it in and all it does is a short, soft "booop," and that's it. Clock battery is dated 1988. It has an Apple memory expansion card. This is my first encounter with an Apple //. I'm guessing it requires an external floppy or disk drive for a system. What should I do with it? Does it have any value?
