For those longing for these nice HP RPN calculators of yore, have a look at http://www.swissmicros.com/ http://www.swissmicros.com/ . I myself have a DM-16. They're small (credit-card sized) and come with a membrane keyboard, but otherwise are 100% compatible with the corresponding HP models, and have a USB port for serial link.

I'm tempted, especially by the 16 model (have been kicking myself for a very long time for not getting one or three when they were in production), but the membrane keys are a killer. Next to RPN, the greatest feature of HP calculators were their solid, no doubt keys. I did a math heavy semester of general chemistry with my 28S (which I still have, along with a backup I got on eBay) without making a single error, which rather surprised me.
