So you thought only HP still makes RPN calcs Message #1 Posted by Michael de Estrada on 1 Apr 2009, 10:39 p.m. Victor V12 db's collection Although most non-HP RPN calcs went out of production decades ago, you can still buy this one online, although I have never seen one in a store. Of course, HP doesn't really make the HP-12cp either, so I wonder who owns copyright on the code? Michael Edited: 2 Apr 2009, 11:06 a.m. after one or more responses were posted

Re: So you thought only HP still makes RPN calcs Message #2 Posted by Howard Owen on 1 Apr 2009, 10:52 p.m., in response to message #1 by Michael de Estrada There was another 12C knockoff some years ago. I wonder how they get away with copying the 12C like that. I doubt HP still holds active patents on the 12C interface or algorithms, but surely they still hold a copyright on the ROM. So if the clone maker reimplements the machine, then maybe that's legal, or at least lawsuit resistant. Regards, Howard

Lemme see. The HP-12cp is made in CHINA. The Victor V12 is made in CHINA. Heck, if they can get away with fake designer jeans, running shoes and DVDs, why not HP copies?

It might be possible that HP is only a licensee of this ROM and design and that the original Chinese manufacturer has the right to license the code elsewhere.
