Found in a rubbish bin.
Message #1 Posted by Stuart Sprott on 13 Sept 2011, 7:58 a.m.

The company that I work for have just moved to another office. They had been in the last office for over 30 years. In that time a hell of a lot of useless files equipment had accumulated.

The move was a good time to get rid of the useless stuff.

During the move I just happened to look in one of the rubbish bins and spotted HP 32Sii. Naturally I picked it and tried to use it. The keys felt good but nothing happened. Perhaps the batteries were flat; but I felt that would be too good to be true. Anyway I brought some batteries today and it fired up straight away. As far as I can see everything works just fine.

In the past I have never had a 32Sii. The calculator appeals to me and seems easy to program. I do not have a manual, but so far I have been able to work out most of the functions.

My guess is that who ever owned it was just to lazy to get new batteries. I wonder how many good calculators have ended up in a rubbish tip.

Just one question. The face of the calculator is fairly grotty. What is the best fluid and method to clean the face without damaging the original markings?

Whatever you use, be gentle on the first couple of passes or the grit you are cleaning off will buff thousands of microscopic lines into the painted faceplate.

I don't know this because i'm a good calculator cleaner.

Somewhere in my head I can't help hearing "Good judgement comes from experience, experience comes from..." :-)

i use a little De-Solv-It, a citrus based glue solvent and stain remover. a similar (though not quite effective) option is eucalyptus oil. a very light spray, then brush away the dirt with a 1" paintbrush, periodically wiping the brush clean with a rag.

De-Solv-It has the extra advantage of leaving an orangey fresh smell behind!!

Be careful! De-Solv-It may alter the Solve algorithm in the calculator. Make sure that you test that feature and that it gives good results!

PS: Sorry ... hehehehe .. I could not help myself but to respond to De-Solv-It. It was too good to just let it slide by!

Then, I'd recommend Super Solver instead :-)

P.S.
Actually, I'll use isopropanol / methanol mixture at first. If it won't work, I'll use CRC-6-66 then.

Nice find. The manual is available from HP here.

I can e-mail you a little ASCII starter manual for the 32SII if you will contact me directly.
