Is the HP-35S bug free? - Matt Agajanian - 06-30-2013 Hello all,
Some time ago, at least half a year, there were threads about both the 33S and, most prominently, the 35S programming and calculation/algorithm bugs. Although the 33S is no longer available but the 35S is, has HP resolved the bugs which were discussed here?
Re: Is the HP-35S bug free? - Paul Dale - 06-30-2013 I don't believe that any of the bugs have been addressed. The only way to know for sure would be to buy a new device and check for them. I'm not going to waste any money doing this.

Re: Is the HP-35S bug free? - Gerson W. Barbosa - 06-30-2013 These are both bug free and risk free :-)
Re: Is the HP-35S bug free? - Matt Agajanian - 06-30-2013 So, I guess HP got the message and got their act together and doctored up the 35S. Good news!! Edited: 30 June 2013, 7:06 p.m.
Re: Is the HP-35S bug free? - Paul Dale - 06-30-2013 I wouldn't go as far as bug free even though there are no known bugs at present in the v3 firmware.
Re: Is the HP-35S bug free? - Ethan Conner - 06-30-2013 You deserve to own both of them.......
Re: Is the HP-35S bug free? - Matt Agajanian - 06-30-2013 Thanks for the clarification. Which makes me wonder...why did HP drop the 33S? Edited: 30 June 2013, 7:28 p.m.
Re: Is the HP-35S bug free? - Steve Simpkin - 06-30-2013 Quote: Well aside from the fact that it is one of the ugliest calculators ever designed.... I think the biggest reason is that with the introduction of the "improved" HP-35S, there was no longer a perceived need by HP management to sell the 33S. As far as why the bugs have not been fixed in the HP-35S, I don't think HP budgeted for software fixes when they green lighted the 35S. Re: Is the HP-35S bug free? - Matt Agajanian - 06-30-2013 Whoa!! I'm confused here. If the 35S hasn't been revised to remedy the bugs, what's the 'improvement'?
Re: Is the HP-35S bug free? - Steve Fennell - 06-30-2013 It was released 35 years after the HP 35, hence the name. But I suspect HP does not think there's any market for an RPN scientific, which is why we've seen no updates or new RPN scientific calculators since 2007. It's likely still produced because the 33S and 35S are the only RPN calculators allowed on the FE/PE exams in the US.
Re: Is the HP-35S bug free? - Steve Simpkin - 06-30-2013 The HP-35S has the following improvements (aside from cosmetic and improved keyboard feel) over the HP-33S:
* The HP 35s allows both label and line number addressing in programs. The HP 33s had only label addressing. With only 26 labels, it was difficult to write programs making use of the entire 30KB of memory. Re: Is the HP-35S bug free? - Matt Agajanian - 06-30-2013 So, as I understand it, between the 35S from several years ago and the ones available today, there are no bug fixes (which was/is the intent of my initial question). The 'improvements' to which I was referring to are rather nil. But, the 'improvements' to which this thread was leading are only with regards to those of 35S over the 33S.
So, sorry for the miscommunication but, as I can tell, from what you've all been referring to, there are no firmware fixes from the 35S of years ago with its buggy algorithms and program looping glitches to today's 35S. Right? Edited: 30 June 2013, 10:53 p.m.

HP-35S Bug List Re: Is the HP-35S bug free? - Derek Walker (UK) - 07-01-2013 Quote: IIRC Tim's explanation was that the HP35s had been developed by an outside company to meet an HP specification. Which it apparently did, despite bugs being revealed subsequently. The code remained the property of the developer, and so HP had (and has) no way to update it. I think Tim indicated that such a path would not be followed again. Re: Is the HP-35S bug free? - Sylvain Cote - 07-01-2013 The post by Tim is here Re: Is the HP-35S bug free? - Tim Wessman - 07-01-2013 Well that is a nice long thread... Come to HHC, you can ask about this and more! :-) </shameless advertisement>

The LINEQS bug is not fixed as of 3425. Or is it not known? Or not a bug? Edited: 1 July 2013, 2:44 p.m.
Re: Is the HP-35S bug free? - Marcus von Cube, Germany - 07-01-2013 Andrew,
I did my best to resolve the issue. Have you tested it again? It was a problem with the available size of the C stack when the temporary matrices and arrays are allocated in the linear equation solver. The display of an error message was just too much for the remaining memory thus clobbering some status info which caused all kind of strange behavior.
Re: Is the HP-35S bug free? - Andrés C. Rodríguez (Argentina) - 07-01-2013 I wouls say that "the HP-35S bug" is free indeed (or "the HP-35S bugs" are free), because it seems that nobody went after them, or otherwise chased them, in the last five years!
Please disregard any idiomatic mistake.
Re: Is the HP-35S bug free? - Matt Agajanian - 07-01-2013 Thanks and thanks!! Thanks for the full clarification and thank you for bearing with my questions
Much appreciated.
Re: Is the HP-35S bug free? - Eduardo Duenez - 07-04-2013 What about the bugs in the 15c-LE firmware? Those are potentially user-fixable by re-flashing, yet no firmware update has been released (please DO correct me if I'm wrong!). Is HP caught in intellectual property land-of-doom (by having outsourced) in the case of the 15c-LE as well??? Eduardo PS: Sorry for hijacking the 35S thread, but discussing this 15c-LE topic seems appropriate enough.
