New -21 and -25 apps for iPhone Message #1 Posted by Eric Smith on 5 Mar 2011, 6:53 p.m. Maciej Bartosiak has ported my simulation code for the -21 and -25 calculators to iOS, so they may be used on the iPhone, iPod Touch, and iPad. The apps are RPN-21 and RPN-25. I hope no one objects to my posting this announcement; I thought some of the regulars here might be interested in these apps.

Re: New -21 and -25 apps for iPhone Message #6 Posted by gene wright on 6 Mar 2011, 7:56 a.m., in response to message #5 by Eric Smith Heh. An HP 27 and/or HP 29c would be nice. ;-)

Re: New -21 and -25 apps for iPhone Message #8 Posted by Namir on 6 Mar 2011, 9:12 a.m., in response to message #5 by Eric Smith I don't mind paying a reasonable fees for these emulators.

Re: New -21 and -25 apps for iPhone Message #10 Posted by Walter B on 6 Mar 2011, 8:46 a.m., in response to message #1 by Eric Smith Nice looking for sure. BTW, please note all shifted functions are located below of the primary operations :-) For edition 1.1 I'd suggest an improved exponent format - e.g. sin^-1 looks a bit primitive spelled this way IMHO. And a capital Pi is used ... :-/

Re: New -21 and -25 apps for iPhone Message #11 Posted by Vincent Weber on 6 Mar 2011, 10:32 a.m., in response to message #10 by Walter B Great app ! A couple of comments: 1/This is obviously not a HP-25C: killing the app resets memory; on Iphone 4 this is not much of a problem, you can use multitasking to keep the memory state, but still - is there any plan to upgrade it to a HP-25C in future ? 2/I think there is a bug: I never owned a HP-25 but I think it is supposed to display the next instruction to be excuted if "SST" is held down (and then, to excute the instruction). Here, nothing of this kind. Is this a bug or an intended behaviour ? Would be awsome to have the 34C (and of course, the 65 and 67, if ever their card reader behaviour is reversed-engineered...). Cheers, Vincent

Re: New -21 and -25 apps for iPhone Message #12 Posted by Eric Smith on 6 Mar 2011, 4:10 p.m., in response to message #11 by Vincent Weber You're right about SST on the 25. I'll talk to Maciej about that and continuous memory. Thanks! Eric

Re: New -21 and -25 apps for iPhone Message #13 Posted by Vincent Weber on 17 Mar 2011, 6:22 a.m., in response to message #12 by Eric Smith Hi Eric, Thanks, the new version is on the Appstore and corrects the 'SST' bug ! It does not implement continuous memory, though. Could you maybe tell us what is scheduled for Nonpareil for Iphone ? Especially: -If the calculators that are already in Nonpareil, especially the 34C and 33C, could be soon on the Appstore ? would be great ! -If the calculators that are not yet in Nonpareil, but that you have been mentionning in 2008 as almost-ready (especially, the 67 and the 29C) could come soon as well ? -and if other calcls (especially the 65, would be great) could come and when ? Would love of these beauties on my Iphone :) Thanks and cheers, Vincent

Re: New -21 and -25 apps for iPhone Message #14 Posted by John B. Smitherman on 6 Mar 2011, 12:17 p.m., in response to message #1 by Eric Smith Great work! Unfortunately, my original iPod Touch is stuck at OS 3.1.3 so I'll have to wait until I upgrade to a newer "i" device. Regards, John

Re: New -21 and -25 apps for iPhone Message #15 Posted by Eddie W. Shore on 12 Mar 2011, 5:39 p.m., in response to message #1 by Eric Smith I have downloaded the 25 on my iPad. The calculator looks nice. A help file would have helped. However it is nice to play with an HP calculator in 1970s style.
