Buying it on a device with the Play Store and then installing Aurora Store while using that same account is probably much quicker, if you have a phone with the play store available.
The problem is, if you don't own a cel phone, Google Play will not let you create an acount to download anything.

Not just a phone. If you've owned any android device (other than a Fire tablet) at any time since Android has been in the marketplace you'll have a Google Play account.
If the Amazon Fire Tablet is your first Android device you'll be stuck (and that's when you'd have to resort to jailbreaking and suchlike).
There's a great variety of 8" Google Play compatible tablets in the marketplace for $50-$150 that have more than enough processing grunt for calculator emulators (the form factor is great for calculator apps too).
It was recommended to Thomas that he lists his calculators on the Amazon Fire Store in the main Plus42 thread, and I'm sure it's something he'll get to if he feels it's an apt option.
BTW, why is it not possible to paste from the buffer in every ALPHA-mode input? For example after XEQ ALPHA or STO ALPHA.
It would be a nice minor improvement too.

If that's an actual question, I encourage you to take a look at the convoluted mess that is the Free42 / Plus42 keystroke handler.
But seriously, it's not an unreasonable idea, I'll make a note of it.
Useful only on the HP-17B II, but might be a good equation test anyway. I am glad it is working now (it wasn’t two months ago or I had done something wrong).

SGN() was broken, and that was fixed in the latest release (1.0.9).
