OT TI-59 for the iPhone Message #1 Posted by Matt Agajanian on 30 Aug 2013, 7:17 p.m. Hello all Has anyone seen this app, RCL-59 https://itunes.apple.com/us/app/rcl-59/id597527230?mt=8 If so, what do you think of it?

Re: OT TI-59 for the iPhone Message #2 Posted by Andy B (Australia) on 30 Aug 2013, 9:03 p.m., in response to message #1 by Matt Agajanian I've played with it a little bit. It looks fascinating, I believe the Ti59 sits between the Hp-67 and HP-41c in capabilities. Nice to see this emulation has a program listing view where you can actually read the program (rather than just numeric key codes) and also a printout view. I often get a flashing number situation when playing with it, so it feels a little finicky to me, but I should really read more of the manual and learn how to drive it better.

Re: OT TI-59 for the iPhone Message #3 Posted by Fred Lusk on 30 Aug 2013, 9:54 p.m., in response to message #2 by Andy B (Australia) I agree that the TI59 sits between the HP-67 and HP-41C with respect to capabilities, but it was far behind both in terms of quality and usability. In the early 1980s, three of us from my office spent a week in another office of our civil engineering company helping them finish a big hydraulics/hydrology master plan for a 90-mile-long irrigation canal that they were way behind on. I was handed a TI59 to do some hydraulic calculations using a program that another engineer (since departed) had written. Unfortunately, the program had apparently not been tested by anyone (including the author) and it was buggy. Fortunately, I had his notes and the manuals to the calculator, so I attempted to fix it. ARRGH. I ended up writing my own program for my HP-34C (the SOLVER was a BIG help). If I had owned a 41 at the time, I probably would have used that instead and incorporated a programmed root solver…this was pre-Advantage Pac.

Re: OT TI-59 for the iPhone Message #4 Posted by Matt Agajanian on 31 Aug 2013, 12:04 p.m., in response to message #2 by Andy B (Australia) What were there other impressions you got from the iPhone app? Does it have, like 'Legendary 67' a mag card library you could build?

Re: OT TI-59 for the iPhone Message #5 Posted by Namir on 31 Aug 2013, 12:05 p.m., in response to message #1 by Matt Agajanian I just got the iPhone version. I already had the Android version. Both are very nice. Namir

Re: OT TI-59 for the iPhone Message #6 Posted by Les Koller on 31 Aug 2013, 5:39 p.m., in response to message #5 by Namir Could not find that exact name on the Android Play store...what is is called exactly, or has it been removed?

Re: OT TI-59 for the iPhone Message #7 Posted by Namir on 31 Aug 2013, 11:17 p.m., in response to message #6 by Les Koller Try TI5x

Re: OT TI-59 for the iPhone Message #8 Posted by Les Koller on 1 Sept 2013, 2:12 a.m., in response to message #7 by Namir Thanks, that is what I was hoping. I do have that one.

Re: OT TI-59 for the iPhone Message #9 Posted by Eddie W. Shore on 1 Sept 2013, 9:05 p.m., in response to message #1 by Matt Agajanian I have it, but I have not had the chance to play with it yet.

Re: OT TI-59 for the iPhone Message #10 Posted by Matt Agajanian on 2 Sept 2013, 3:26 p.m., in response to message #9 by Eddie W. Shore Hi there. When you get to it, let me know what you think of it. Thanks

Re: OT TI-59 for the iPhone Message #11 Posted by Eddie W. Shore on 4 Sept 2013, 8:57 a.m., in response to message #10 by Matt Agajanian It runs like a TI-59. Tapping at the top left will show the program steps that are stored, up to 999. Tapping at the top right will access the "printer". I am not sure if running speed is set to be close to the actual TI-59. Finally, I have to learn to add INV RST to the end of TI programs. So far I don't notice any bugs. Eddie
