I'm not even sure which subforum this is supposed to go in, but... I just bought a Mac SE/30 for about 10 bucks but I'm a PC user to the core and I don't know what I'm doing after I flip the se/30 on. There's a little blinking floppy disk icon and when you insert a disk it ejects it and the disk icon has a little X on it temporarily instead of a question mark. What am I supposed to do? What needs to be on the disk I insert?
