Hi friends,
I’ve been playing around with the HP-41C and it got me thinking — what’s the most fun or unexpected program you’ve ever written on it? Maybe a small trick, a clever routine, or just something that made you smile.
I’d love to hear your stories and maybe learn a few new ideas along the way.

As for actual fun, I do get enjoyment from whipping up solutions to problems in my work; but one program with no usefulness other than fun was to use synthetic tones to make it sound like a phone ringing when I'm with someone else, and pretend to be answering a phone call on the calculator.

Thanks for catching that. I've removed the links in all four posts of this (ab)user, and banned him or her. I'll refrain from deleting the posts for now, since they were mildly interesting (outside of the spam links) and got some replies (including my own). I'll watch more carefully in the future, now that I know yet another trick they'll try.
