2015's calculator anniversary - the SR-52

[isanchez]

HI,

I have a sr52 with all the stuff: box, case, standard pac, maths pac, stat pac, ee pac, books, programming forms, etc.

I repaired the card reader and it works fine but it took quite a lot of efforts, as I didn't find the proper o-rings (standard size), like for the hp41, 67, 65, 97...I had to use a dremmel to "resize" the new tracking roll inside the reader to the proper diametre...(by the way, I don't know the English term, but if it is of help, I used one of those solid rubber 10mm diam. rings used in the faucets)

About the hardware quality, it cannot be compared with HP at all (I don't talk about the software).
Inside everything looks fragile (card reader quality is an example), battery terminals, the cards are very sensitive to humidity, etc.

...but I love it!

My best wishes for all you this New Year.

Ignacio
