Buggy Hewlett Packard 15C Scientific Calculator iPhone App?

[Oulan]

Hi,

I am interested on a list of the original HP15C bugs.
I already dis-assembled and partially commented the rom of the 15 to patch it to have more memory (as swissmicro did to have more memory too).
I still not have released it in go15c as there are some mis-behavior for matrix larger than 9x9 (and it is not really that useful, use go42s if more power is needed).

Perhaps some original bugs could be corrected ?

P.S. PSE behavior is correctly done if you write a correct emulator
