Problem with my 11c

[hayesbd]

Geoff,

Thank you, thank you, thank you! I found an unsoldered terminal! I'll get it back in order and report my results.

This calculator has been through a lot with me. I once accidentally dropped it into a bucket of house paint and, of course, had to rinse off all the latex paint, thoroughly soaking it inside and out. A week later, it was dried out and working fine once again!

I have used this calculator almost every day of my working career for the last thirty odd years. I am amazed at how discombobulated I have been trying to use a crummy TI algebraic calculator (I use this term loosely here) for the last few months.

Since I have many years left (I hope), I want to procure a backup if this one ever dies permanently. I was leaning toward another 11C/15C, but have seen a lot of glowing reviews about the 32SII as well. What would you folks recommend? I really don't program much, preferring MathCad or Excel for that. I just want a reliable/ergonomic/durable scientific RPN calculator.

Thanks again,
Brian
