I get "about:blank#blocked".

Here's the original URL: http://reviews.ebay.com/The-HP-vintage-p...LISTINGS:1

But I'm afraid, "It's dead, Jim."

As I recall, the guide did not contain any information on grading calculators. It did provide an "average" sales price, but similar condition calculators can sell for a significant difference in price depending on whether or not the calculator includes a case, manual, QRG, or box.

What the guide did provide was a list of all the variations for a given model including battery type, key color, bezel type, and number of feet.

When assessing the value of a calculator on eBay, I look at the physical condition, including the battery compartment, what accessories are included, and what similar calculators have sold for which is not necessarily the BIN price.
