HP-32S: How do I open the casing without damaging the calculator?
Message #1 Posted by Eric Edwards on 15 Mar 2002, viii:36 a.m.

I have a HP-32s that has all the rightmost keys not working. Since I have never opened a calculator like this earlier I was hoping that somebody here had done it and knew how to exercise it without damaging the calculator. I see no screw holes similar the Hp 12C etc. Does anybody know what could be wrong with the keys? Do you lot think information technology would exist fixable when/if I can open the computer. Eric :-)

Read Paul Broggers articles on RAM upgrade for a 42s. (only need to read the part on opening the calc)

His instructions are flawless. (Same housing).

Good luck,

Thank you all! I took it autonomously as described past Paul Brogger. (Couldn't take done it without his help, thanks Paul.) Subsequently a petty bit of niggling taking out the PCB I constitute the error. All keys are working over again!!! Actually I had 2 HP-32S with excatly the aforementioned problem and they both were fixed the aforementioned manner :) But how exercise I put the casing back together again? Preferably then information technology can be openened without besides much difficulties in the future! Any ideas? Eric

Mr. Edwards:

I've taken apart simply about every Pioneer model I own. They're easily made to stick back together, if you haven't drilled the upper rut stakes too deeply.

I just trim the mushroomed ends of the 4 lower heat stakes so they're just slightly larger than the posts themselves, and pop the sides back together again. (Don't cut the mushroomed ends off or shorten them -- but trim their widths and so they squeeze dorsum into the holes in the metallic backing plate.)

The friction bail seems to stand to most normal employ. I dropped one in one case and i side separated slightly, simply the halves didn't come completely apart.

If the top terminate doesn't stay together satisfactorily, you may use a soldering iron to melt the posts and holes together again.

The 32S is easily my favorite HP model for daily use. They're definitely worth the endeavor to keep 'em running.

I hope things work for you -- good luck!

One more matter. I have never used the HP-32s and have no manual. Doesit have a selftest like the HP 15C? Keyboard and CPU? I could not notice anything on the HP-32S article itself, perhaps it is somewhere else? Eric

My mistake. Found information technology under: http://world wide web.hpmuseum.org/features/32sf.htm See: notes as I judge with all featured calculators at the HP-museum

"press and hold the yx key and printing the ON/C key" etc...

One past without problems only the other still take some problems, needs a litle bi uo adjustment I guess. Eric

These machines were never meant to be opened or repaired. Once you open up the machine, repairing the keyboard is just near impossible. Information technology is heat staked down with a zillion melted plastic rivets. Fifty-fifty if y'all cut them all loose, getting the keyboard dorsum with expert feel is highly unlikely.

I take had some success past imersing the machine in an ultrasonic cleaner. Repeat three times with distilled water. Dry out for 24 hours in an oven on low (< 140 F) heat. Since this is a risky performance, just recommended equally a concluding resort... like a dead row of keys.
