I figure somebody will pop in and tell me what they go for these days.  It was
originally $500+, I think, then when it fell to like $200 I bought it.  I don't
know whether it has "antique" value like some old computers, or whether I'd be
lucky to get $50.  (Below that, it wouldn't be worth the trouble.)
