Here are a few things I have that you don't run into every day. I was wondering how these things rate on a rarity scale. Mac SE-double disk drive (Ah, my first computer), and of course the requisite copies of Crystal Quest, Alice, etc., that run on it. Performa 6320. I've never actually seen another one of these. Apple Corporate sent this to me as a replacement for what seemed at the time to be a buggy 6300. Man, I need to dig through some of my dad's old disks before he throws them out. There might be gems in there...Are there examples of old software that are rare/collectible?
