I've been given the chance to buy a II+. As I primarily stick with Macintoshes this is a bit out of what I know, but feel like I should have an Apple II of some sort somewhere in my collection. I'm trying to get some more details on this one, but I do know that it's currently working, has a Z80 card, and "all the software you could imagine." I know that plastic condition is important on these, but is there anything else I should check out before buying? Unfortunately, the computer is currently located in far Eastern KY and am relying on a trusted friend to get me details on it(it belongs to his girlfriend's parents) but primarily need to know what questions I should ask..and from there what a fair offer would be.
