Ratings and reviews

ABANDONWARE! DOES NOT WORK ON MODERN PHONES I've been using this calculator for many years and the (free) 33C before that. Loved them to death, as they were the best HP emulators out there. But I've upgraded my phone, and this does not function properly on the LG G7! I constantly have to "rotate" the image once to fix the display, and it crashes frequently. It hasn't been updated in years - none of the Go series of emulators have - so avoid it. The author has abandoned it, so you should too.

It has to be fully reviewed for full screen option in android 9.0 Screen issue when open the app. For the user is tricky to solve the issue just using the option rotate, but still works. Developer does not seem to care about the app, since last update was on 2014!!!

I really missed my 15C, this does work, but it takes a while as the author doesn't tell you where to find the ROM, or the nonstandard way he named is program file and directory. So it takes a bit of googling to find the Rom and more futzing to find this folder. Two minutes of time spent on his linked webpage giving clear instructions on his webpage and he would have gotten 5/5

What's new

Support for Android 14 and above with the addition of the choice of the ROM import directory (15c.obj file)
On first launch choose a directory in which the ROM file 15c.obj is located
Then quit the app. On next launch, hold 'ON' until 'Pr Error' is displayed
