  • 4. August 2009 - I am very busy with my job at the moment and will not have time to work anything on the project until end of October. I am sorry for that, but first priority is on my job.

  • 27. July 2009 - First of all, I like to thank all of you for your response! Sorry, if it takes me long to reply. I am really busy with my job these days and have very little time for the project. I am currently putting together a very minimalistic version of the emulator, which I will try to get in the App Store. I haven't applied for the developer program yet. Also it is still unclear to me, whether the app will be allowed. Make sure to check back every now and then, since I plan to put a little demo on youtube soon!

  • 23. June 2009 - I am currently programming an HP48-emulator for the iPhone and have my first version up and running (see above). Due to very limited spare time I am unsure when and if this will make it ever to the public.
    Further it is unclear, whether such an application will be allowed there.
    Also I am not sure about demand of such an application. Do you need an HP48-calculator on your iPhone? Drop me a line and let me know!
