OT TI-59 for the iPhone



#12

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?

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.

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.

What were there other impressions you got from the iPhone app? Does it have, like 'Legendary 67' a mag card library you could build?

#16

I just got the iPhone version. I already had the Android version. Both are very nice.

Could not find that exact name on the Android Play store...what is is called exactly, or has it been removed?


#18

Try TI5x

Thanks, that is what I was hoping. I do have that one.

#20

I have it, but I have not had the chance to play with it yet.

Hi there. When you get to it, let me know what you think of it.

Thanks

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.
