Display test ... not 100% correct?
Posted: Fri Oct 02, 2020 2:42 pm
Hi!
Whenever I get my hands on a new 41 calculator (let it be a real thing, an emulator or something else), I always try to download the PPC ROM and run the display test program ("DT").
On a real calculator, and on some PC emulators (like V41) this works fine, eg all segments are lit:
But on others, like the DM41X or the Android emulator go41cx, it only shows some of the segments:
(I would have expected that the alpha register would be the same as the original, the x-register is as expected.)
Is there someone who can explain this difference?
Best regards,
Thomas
