TI made so many 4a's (and firesaled them) that they aren't really collectables. They are cheap cheap cheap on ebay. maybe one day they'll be worth something, but I have my doubts. there are probably many that are just sitting around unopened still in their original boxes because people bought them for what they thought was cheap as "might as well get one as a backup". but yes, I'm found of it as it was my first computer and grew up on munch-man and parsec (amongst other things)
