I used a 58C in 1979 while at Engg. College (at U of K). I found my calculator a while ago and amazing it is still working! I have a 3 Library modules (with the chips) and was looking for a few more. I wonder if there were a few new-found libraries in some dusty walled off storeroom at TI which I may buy. At the moment, I have the original Master (ML), the Aviation (AV) and the Marine (NG) Libraries . I still use them and create short programs. It brings such joy, and takes me back to when I was 18 again!
PS: I do stop at yard sales just for them, but have come up empty so far. ;/

In reply to LeonardEllis:
Thanks so much for your prompt note. I checked the link and drew a blank (the 58C may be too old). In any event, I have emailed Cust. Svc.. Let's see what they suggest.
In reply to Dan Ruparel:
Glad you sent an email to CSC, as E2E is for IC engineering and design questions, there would not be any expertise concerning calculators.
I did find a TI-85 Guidebook: https://education.ti.com/en/guidebook/details/en/8D7A30C057FB4063B9F7BF0C15194A14/85 , and then I saw I was dyslexic, no TI-58 info I could find!
Good luck in your search.
