Help I just got a AppleIIe with a 80col/64k memory card and a I/O card.When I turn it on Apple//e appears at the top of the screen and the it just sits there. Do I need a floppy to boot off of? I have a DOS3.3 disk. I thought AppleIIe's had a built in operating system in ROM. Any information anyone could provide would be greatly appreciated. Thanks Terry
