Hey, I have a Performa 578, c. 1995 a friend just gave me. I was wondering if it's worth anything. I can't find any models on eBay to get an estimate on how much they sell for (which I know is probably because it isn't worth anything). Based off when it was made I don't think it's enough of an "antique" to be worth much at all... is this correct? It still works. It's in fair condition and still has the original box and things. Would it be worth it to try and sell it?
