Re: Which side of the glass case do the Hp's belong on? Message #15 Posted by Valentin Albillo on 7 Sept 2005, 6:34 a.m., in response to message #1 by Richard Zajac
Hi, Richard:
I own more than a hundred vintage calculators, mostly HP and
SHARP BASIC handhelds, together with their manuals, accessories, etc.
But for three, all of them are safely stored within an enclosed, humidity-controlled cabinet in a relatively cold place, each particular calculator inside a hermetically thermo-sealed plastic bag. This keeps interaction with light, heat, air, and humidity to a minimum. Before storage, each calculator has been carefully cleaned up, both inside and outside, and of course with no batteries or power cells in them. This guarantees as much as possible that except for time itself, most aging and degrading agents are left out.
As for the three models excepted from this treatment, they are an HP-15C, a full HP-71B, and a SHARP PC-1350. All of them are in very good condition (the 71B being actually mint), and see frequent use. The HP-15C is further protected by being tightly enclosed in a very clear plastic bag, which prevents any physical contact with its surfaces, thus avoiding stains, fingerprints, dust under the display, moisture, etc., while allowing perfectly comfortable use.
The other two models are not so delicate and do not require such extra protective measures, they're simply treated with care.
Overkill you might think ? Not so. These measures ensure that my valuable calculator collection stays in pristine condition for years to come, so that I can take out any of them some years in the near future and have the extreme pleasure of holding in my hands a, say, pristine, not-a-single-dust-speck, not-the-slightest-blemish, shiny and new HP42S, HP-15C, or HP-41CX, say. Proceeding otherwise I would be denied this exhilariating experience.
Do I not miss having them at hand at all times, using them, etc ? Well, I *do* have an HP-15C, full HP-71B and SHARP PC-1350 available at all times, and they do get used. As for the rest, I did make extremely good quality digital pictures of all of them, and can look at them at will.
And re using them, with such fantastic emulators as V41, Emu42, Emu71, Nonpareil, and SHARP PocketEmu, to name a few, my vintage programming needs are more that fulfilled, and with better facilities to boot (keyboard, mass storage for calculators that had none whatsoever, etc).
Best regards from V.
