Back in 1987 a professor of mine purchased an HP-28S which he immediately loaned me after purchase to play with over Christmas break (he not being an HP person.) After I gave it back to him, he placed it in his desk, and there it sat..... for 22 years, never again touched. He gave it to me this last weekend, and, with fingers crossed, I opened the battery compartment. Perfect. No leakage! A mint unit with only about 20-hours of my own time on it. Woohoo. :)

Nope totally dead. But with fresh batteries, the beep with "Memory Clear" was the best sound ever. :)

I thought the first HP-28Ss didn't show up until January of 1988?

It could have been winter break of 1988 (by the looks of the serial number). My mind is going. Daisy, Daisy, give me your answe.... Edited: 28 Apr 2009, 1:08 a.m.

Quote: Dave, please stop... And I thought I was the only one confusing dates. Is there a way to age gracefully? That beep, or the clock missing a few minutes in years, are welcome sights/sounds in the 28S. Some time ago I recalled my 28S from storage in a garage, after a few years (can't remember how many.) Not only it lighted up, the clock was running. From what I was told in this forum, the time difference was not significant. If only the battery door was not so brittle...
