Probably not that impressive an age compared to some, but what I find amazing is that there's still no better tool for working in hex/binary/decimal and flipping between word sizes and complement modes.

Agreed. I sold mine ... only because someone was willing to pay a hideous amount for mine.
I soon regretted it because as you said there really is no substitute, until learning (here) about the amazing WP-34s. It's overkill for the task, but nothing else comes close to emulating a proper 16C. The WP-35s does it perfectly. Better, in fact.

Oh, great... thanks, guys! I thought I'd just catch up on some of the older forum posts, and NOW there's ANOTHER calculator I absolutely must have! :-P

I finally found a near-mint 16c last year for about $100 and jumped on it. Always regretted not buying one when they were brand new. And I agree, nothing else I've owned is quite like it.

Now, how much money do I have accumulated in my nickels-and-dimes jar for that 34s?
