Why no version for the 2.15 ROM for the 49G+ and 50g? This is the latest (and final) version and believe 2.15 is by far the most common version in use today.

[Gerald H]

I don't have a 50g with 2.15 ROM.

I believe 2.10-7 is the same, except for the Apps, having the Geometry App but not the one for data collection.

Perhaps someone could test Exmath on a 50g with 2.15?

[Gerald H]

I have cursorily tested Exmath on Android go49g+ OS 2.15 & so far all seems OK.

Why not update your 50g to ROM 2.15? Although there is always a small chance a new version could add a new bug, this version definitely fixed many bugs, so why not use the better version?

Is there some advantage to using the older version (other than you are more familiar with it)?

[Gerald H]

Well, 2-10-7 does have the Geometry App, I consider that a small plus.

I don't know if any bugs were removed between 2-10-7 & 2.15. In the .pdf file included with 2.15 there is a Change Log list, but no bugs, except for that introduced in 2.14, have been fixed since 2.10, so I presume 2.10-7 is as bug-free as 2.15. Do you have any further documentation?

In this thread

http://www.hpmuseum.org/forum/thread-9195.html

posts 10, 11 & 15 Joe Horn believes my 50g is faster than his. I don't know how great the variance in speed is between different 50gs using the same OS, nor indeed between different OSs.

Perhaps 2.10-7 is faster?

[Gerald H]

I forgot to say that I also have 2.10-7 installed on my 49G.

[Gerald H]

Both 2.10-7 & 2.15 have this Easter egg:

[Gerald H]

But this Easter egg

seems to have been removed in 2.15, at least on the go49g+ emulator.

Still here (50g #2.15).

Confirmed on both a 50g and 49g+ running 2.15.

I think I recall seeing a list of bugs fixed in 2.15 but can't find it now. Perhaps I'm mistaken about that, but I do know at that stage, HP was only patching the 50g ROM if absolutely necessary (as there was literally no free ROM space left, so every single change took lots of work) so I'm fairly sure the 2.15 release was driven by bug fixes, even if they weren't acknowledged in public docs.

Still here (50g #2.15).

Also present in Android emulator, don't know why I didn't find it yesterday, but doesn't seem to work correctly, causing reboot.

[Gerald H]

Should anyone install the library I would be grateful for feedback, particularly if there should be any bugs.

I've used the library for some years, incrementally improving & adding functions & not noticed any bugs for some time.

Thanks Gerson, I knew I read that somewhere. Probably should have looked first in the exact place it should be...

The documentation says that after executing the EXMATH command, numbers are entered by pressing the "the B key (2nd menu key)". But that's not true for the 50g version of the library, which shows the "%" function on the B key. I can't find any key combination that lets you enter numbers.

Also, the doc says that the 5th menu key is Exit. It's not.

So I can't enter numbers at all, and I can't exit. Please help.

[Gerald H]

To ENTER a number:

Right Shift (Orange) then F1

demands a mantissa & then an exponent.

To EXIT:

Right Shift (Orange) then F6.

A further change is the position of SWAP which is now

Right Cursor Key.

Thank you, Joe, I'll update the documentation.
