Improving the solver experience on the 41C

Thanks, Ángel. That is a nice simplification and space savings. I'll check out the Interchangeable Solutions ROM as well. It's not on TOS, but I found it on Geir's site.

It's too bad the 41C doesn't have a 2-line display as that would improve the user interface. However, I happen to have a 2-line OLED display that fits perfectly where the existing LCD sits, and a small ARM processor board running nonpareil...
