My HP Calculator Collection

[PANAMATIK]

I have cataloged my HP Calculator Collection with images, together with a summary of my repairs and repair attempts, which are already posted here in various threads. If you are interested to read you can download this file from my website

Taschenrechnersammlung.pdf.

The first part is written in german, but the more interesting repairs are in english.

Thank you Bernhard, very complete and interesting.
Fun to see that you only own one 41 model, but the reason is given (auf Deutsch).
(and that you own Bruce Lee's HP27, that's a real collector piece!)

The repair chapters are absolutely impressive, it's nice to have this reference in one single document.

@ Bernhard: It's almost summer vacation, time for a bridge. I posted your list in Darknet once. Let's see what happens.)
Greetings from Allschwil (NO, I have no collection)

After having documented my collection now, it will be no longer accessible in real items. Perhaps it can be excavated around 3000 by future archeologists. They also will dig near Basel but find nothing, because river Rhine has swallowed everything hundreds of years ago.

Fantastic, Bernhard. But then again, I always am amazed at your work. Especially the HP-01 development. You have 12 of the HP-01 watches?! That's quite a collection, indeed!

The german text explains, that I do not own all 12 HP-01 watches in the picture. About half of them were accidentally accumulated for repair at the same time and allowed me to shoot this remarkable image.

Nice to see the Aristo scholar LL. Had exactly the same at school in 1976, a year later we moved to the TI-25 so just one sliderule year but I think I still know how to basically use it.
Used the TI-25 for 3 years changed for a TI-50 used that for 2 years and after that bought the HP-41 and never looked back.

Perhaps today you looked back, didn't you

I had also the Aristo Scholar in school, the reason for having it in my collection now.

I certainly did, but I never looked back at the TI calculators, they were not bad but nothing beats RPN .
The 67 and other led calculators were never popular in my generation (I am 57 now) because the first calcs allowed in school were the LCD ones. So opposite from you I am more a 41 than a 67 fan.
I read similar stories about 42 and 48 fans, could never get used to the 48 but some are crazy about them.
Thanks for showing the collection and also for sharing some repair tips.
