HP-16C

I've wanted an HP-16C for a very long time. I should have used some of my lawn mowing money to buy one when I first discovered them, but I didn't. Then HP quit making them and no one has made a calculator like it again. Sure, all of the features exist on other calculators but they're buried deep in menus. The HP-16C has the hexadecimal numbers, shift, rotate, logical operations and many other functions I use during my day on they keys.

Sure, I can find them on eBay and other auction sites, but I've never had good luck there. But what about building a clone? I can certainly write the software and I feel confident working out most of the electronics. The display, keyboard and case are the biggest hurdles but they aren't insurmountable.

Hmmm... Before I get too deep perhaps I should find someone I can bounce ideas around to make sure I'm not about to jump off the deep end.
