i have an old apple //e platinum how do i use it it has hard drive/keyboard screen and 1 large floppy drive?

Answer 1

OK, first thing is, there is no actual hardware nor software out there on the primary market; secondary markets like eBay would have the stuff but you need actually knowing what's to get.

Second thing is sell it off eBay to a private collector if that makes sense to you; Apple II machines are still around for sentimental reasons.

Apple II series software is bootlegged online, not sure of the legality of whatever you got online, nor how to get it to an ACTUAL hardware, starting with Apple DOS to get for it.
