Greetings!
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!
Many thanks!
Dan
PS: I do stop at yard sales just for them, but have come up empty so far. ;/
