Message #5 Posted by Les Wright on, 10:59 a.m., Anyway I'll recommend the calculator for sure to the iPhone owners I know. This will be a (another) good reason for an iPhone if it won't be such an expensive toy, at least in Europe. That's definitively looking very nice, and your alpha-report is mouth-watering. Message #4 Posted by Walter B on, 11:37 a.m., He DOES however hope to keep the final cost down, but, in order to cover certain costs attached to disseminating apps through Apple, he will need to charge something. I got the impression from Thomas there are a few weeks work to do yet, and he is busy with other things. Message #3 Posted by Les Wright on, 11:22 a.m.,ĭon't count on the final version for Xmas. If not, I understand.īesides the free Voyager emulators from Crimson Research, Free42 on iPhone will make a nice Christmas present. Would you be so kind as too post a screenshot? (Hold the Power button in, then press the Home button. Re: Free42 port to iPhone looking AMAZING! I just wanted to share that the project seems very real and seems pretty close to completion, and for those of us who love the the Windows, Linux, Palm, and PocketPC versions this is shaping up to be even better. I think Thomas is hoping to see this widely available in the new year. I know that those interested in emulators/simulators are few around here, and that the subset of iPhone emulator/simulator users is smaller still, but I still wanted to express my great excitement. I still am not comfortable with the Perl script, which would solve that problem. Working with HP42S program text listings with hp41uc is a bit of a challenge when the program contains commands that are not in the HP41 native command set (e.g., in 42S programs I use recall register arithmetic a lot to save steps-RCL+, RCL*, etc.). As we know from i41cx+, getting RAW format program files OUT of the handheld is not easy. Thomas is hoping to implement some sort of file I/O that does not rely on the HTTP protocol that works so well with i41cx+, but advises that he isn't clear yet how to do that since the iPhone SDK is impervious to so many things easily done on other platforms. The integrator and solver work very well, as far as I can tell (since bugs were worked out in the other ports I would expect them too), and given that tons of memory is accessible one can allocate huger arrays than one would ever reasonably need in a handheld-i.e., on my iPod touch, allocating a 1000x1000 matrix takes a couple of seconds, but it gets done. I have hand-entered a couple of my shorter favourite HP41/42 programs, and they run as expected. Indeed, these are features of Free42 I have always enjoyed compared with other simulators and emulators-rapid speed and high internal precision. The simulator runs at the native speed of the processor, which means it is very fast. are implementing only the BCD-20 decimal version with 25-digit internal precision (Windows, Linux, and Palm versions also have a binary version, but I don't use it much, and I don't think it will be available for iPhone). The new professionally designed skin makes for excellent touchscreen accuracy, and there seems to be excellent visual and functional integration with the iPhone 2.2 OS. The present version does not have program I/O yet, but, as far as I can tell, things look pretty darn functional and the simulator looks and works even better than does my beloved Palm version. When I recently enquired about the status of the project, Thomas sent me the work in progress, making me a de facto alpha tester. I assume that it is known to many that Thomas and collaborators Byron Foster and Susan McKay have been working on a port of Free42 for iPhone/iPod touch. I hope that Thomas Okken doesn't think it out of line for me to share my enthusiasm, but since in his modesty he doesn't blow his own horn much I can't resist.
