SR-52 card reader wheel

[albertofenini]

Hi Jose

I'm really sorry to hear about your loss,
I have lost mine at the end of 2019 so I understand what you are going thru
please accept my deepest condolences ....

Ifyou have time and use every possible distraction to let the mind go for a while
(as I did at the time) have a look at our other thread : SR-52 rebuild project (SR-52 942058 LTA4176)

We really thank you, your original thread and all of the documentation have been of great help and
we have followed it step by step

We restored the keyboard, found a faulty display forever, repaired the battery connectors
glued back the faceplate and got a almost working unit, but as we described in our last post in that thread,
the card reader is not working, may be you can have some good ideas

Meanwhile we will print the documents you have enclosed and look at them

Again, we are very sorry for what happened

take care, we wish you the best !

Thanks for your kind words.
Meanwhile my father passed away on 8-March.


Coming to your thread point, I found some old files in my new laptop related to some information made available by our fellow member Etienne and by Froggy as well.

Some of the Etienne information is still available on his website here:
http://etiennevictoria.com/Sr52_wheel/

I am attaching some draft documents collected from Etienne and Froggy information that was publicly available at the time by the authors, related to the card reader rebuild.
If this violate any rules in this forum, I am sure an Admin will let me know and I will promptly remove it from my post.


Alberto, the SR52 troubleshooting guide contains information on how to calibrate the card reader, but we should not follow that information by the letter, as there are so many calculator variants and I suspect that the manual covers only part of it.

I am sorry for not being able to help you on specifics but as I am currently away from home and to be honest I am also a bit disconnected from this hobby as well, although I keep following all the other members publications.

Good luck and please keep sharing your findings and pictures. I am sure this information will be valuable and appreciated by others as well.
