Hp-42s, what is it worth today?

[Garth Wilson]

Supply, demand, and the ability to match sellers and buyers, sets the price. Before we had the well known auction site, you may not be able to sell it for much because you couldn't find the people who wanted it. Yep, these things go for a lot. My whole set of HP-41cx, HP-71B's, and all the modules, interface converters, accessories, books, etc. could fetch me several thousand dollars, but they're worth more than that to me, so I don't sell them.
